I am entering late in the discussion and I can't say this "crazy" idea didn't pass from my mind but I can't even find a good source of raw/fresh cow milk let alone mother's milk
and the kids are already passed that state. I appreciate the effort though in the name of providing cheese to lactoz intolerant babies.
Now, I believe mother's milk would be somewhat equal to goat's milk as goat's milk has these smaller fat globules which are digested easily than the cow's. People who can't drink cow's milk are using goat's.
As goats milk gives a more fragile curd like the mother's milk even with the added CaCl2 and milk powder, I think it is fair to say that mother's milk should be handled like goats milk. Maybe even mixed with goat's milk would give a better cheese but lactoz comes into question here for intolerant people/babies.
The protein powder used may also be selected as pea protein isolate powder so that lactoz intolerant people can consume this cheese.
Also "iron" which is in cow's milk does not exist in mother's milk. I am not sure how this affects the coagulation but it is one of those things that is missing in the mother's milk.
