I see the value of your proposal. If we had such a study, we would have a standard against which to measure food quality and viability. We would have something we can direct new owners to who have food questions. Until then, they have to navigate the minefields like we do. Some people are great at giving advice and some, while having some good advice, have a natural talent of seeming arrogant while they give advice.
Until then, there's a few things that an owner can go by. Unless your dog has kidney problems, find a food that has a meat meal as the first ingredient. Use the AAFCO guidelines for your type of dog, such as large breed adult. There will be a percentage of protein and fat and fiber and moisture that your dog will need, based on size and age. Find a food that provides at least that amount, and one with a little more won't hurt, either. To that end, a food with a statement that it was found to provide the proper nutrient profile for your size and age of dog through AAFCO guided feeding trials is a good place to start. It doesn't automatically mean that your dog can handle that food. It may have ingredients that give your particular dog fits in its system.
I have a pet theory, if you'll pardon the pun, that the simpler the food, the better, even in kibble. But even that experience will vary from dog to dog. Another pet theory is that dogs of different sizes handle different ingredients differently. A corrolary theory that dogs with inherited sensitive stomachs may have a problem with some foods.
Then, there's also the ancient engineering principle, if it works, don't fix it. In the same breath, use the scientific method. Observe, hypothesize, observe some more and change hypothesis if data changes require it. By that, I mean, if you buy a food for your dog that looks good enough for you to eat and your dog has problems with it, don't keep feeding it because you believe it's a good food. Feed your dog what they can handle. Find out what it is they need and stick with that.
In order to accomplish such a study would require a methodology to successfully handle all the data. The study would take at least 15 years. Necropsies would have to be performed on all subjects, with full lab analysis and a consolidated way of handling blood profiles. To limit the number of variables, it would probably have to be done with pure-breeds, where you can know in advance what genetic defects might affect a certain subject in order to rule out a food issue or determine if a particular food is better for that breed with that problem. Such a study, as some do, would seem to ask more questions than it answers.
