The exact relationship between eating dietary fat and pancreatitis is not known but there a strong association. If your dog has had more than 1 episode requiring hospitalization and the last episode was within 6 months, I would not feed any additional food items beyond a low fat diet. Pancreatitis can be vague and mild to fulminating and fatal. 

All ruminant milk contains 4-6% fat as an as fed basis and so on a dry matter basis the % is above that recommended for dogs with pancreatitis. If the product is fermented which reduces the sugar content, then the fat content will be inadvertently increased (more concentrated). All dietary protein, fats and complex carbs require pancreatic function, so I do not see how fermenting changes that fact.

I would advise against feeding milk.

Sorry .... the recipe is not nutritionally complete or balanced as you have described it.
It is more complicated to make than need be and so more expensive in terms of $ and time while still not meeting their need.
You could make the recipe and send it off to a lab. The minimum profile you are suggesting costs ~$50 but what about the other 25 required nutrients? The full AAFCO nutrient profile (vitamins, minerals, etc) is $2500 per sample.

Yes we could recreate it for you using software and show you where the deficiencies, excesses and imbalances are but then do you know how to fix those? We could do that and fix the problems in a Nutrition Consult ($400)
Or
If your pet has no medical issues, we have an automated module for owners to obtain a balanced diet for their healthy pet.
Go to www.petdiets.com. You begin the process by logging into your account or opening an account for you, your pet and link it to your Vet info, then click on 'Services:’ drop down to “Homemade Recipes’. Select the “See all ingredient options” to see all of our food options or one of several specific diet types (high or low calorie, etc.). You may select ingredients similar to those you are now feeding. The software will re-balance your diet properly and suggest vitamin & trace mineral supplements. The cost is $25 for the first recipe and $12 for each thereafter purchased at the same time. Recipes are available for immediate download after payment.

If your Scottie is on Apoquel you are correct he is being treated for contact allergies known as atopy i.e. molds, mildew, etc. things in his environment. The increase in his itching/allergies with the diet change to Hill’s c/d was most likely not due to the grains as dogs are more likely to be allergic to the protein-carbohydrate complexes in the diet. When diet ingredients are processed, we believe the proteins structure may be changes and there can be reactions between proteins and carbohydrates to form antigens called Maillard reaction products or MRPs. Research in human food allergies are looking at this because we see individuals that have say a peanut allergy and they are fine eating an unprocessed peanut with no issues. When the peanut is processed into a cookie, this is problematic, and the person will show signs of food allergies. We are also learning that food and environmental allergies do overlap in human allergies and “may” to some degree in dogs  There are other components in the pet diet that may exacerbate environmental allergies. His allergy response may have been impacted by the type and level of fatty acids, antioxidants, etc., but again, true grain allergies which are common in people are less likely in our dogs. We still agree though, it is important for you to find a diet that at least does not seem to worsen his allergic response.  

As far as his pH being 8 – urine pH can vary throughout the day. A single urine pH of 8 in a normal healthy, asymptomatic dog would not concern us unless your dog has had some history of urinary tract disease i.e. urinary type stones called uroliths. We would also be surprised to find over the counter diets (OTC) that actually consistently maintain a urine pH because these diets are being fed to healthy dogs and not used to manage disease states such as uroliths. Very low protein diets can cause urine to be more dilute, but again these types of diets are for managing lower urinary disease in patient or other medical conditions. So unless your dog has specific medical issues besides the environmental allergies or atopy, we would recommend finding a diet that does not seem to step up his allergic response, but realize that the ‘grain free’ aspect of the diet is more for marketing to us humans than it is a necessity in most dogs. If for some reason you do have concurrent medical issues i.e. atopy, uroliths, etc. and can't find an appropriate OTC or vet diet that is suitable for your dog we would recommend considering a homemade formulation.  

We do offer now a phone conversation with a nutritionist about your cat or cats and, if you would also like a list of commercial options, we can provide you with a written report/list after the phone consult and a review of the pet’s medical record. There are several dietary options for most healthy pets and the nutritionist will explain, discuss and help you decide. The phone conversation service fee is $200 for 30 minutes, and a copy of that commercial product report will be sent to your primary care veterinarian for their medical records.
