if you could position your center of gravity anywhere, to ensure
maximum braking power, where would it be?

Under "maximum braking" the front wheel stops dead, the bicycle
flips, and the rider is ejected. If you are talking about keeping
both wheels on the ground that is far less braking force than
maximum.

That can be circumvented. Build a bike that positions your center of
gravity below the front axle. You could lock the wheel up tight and
still not do an endo.

No. The important dimension is where the center of mass is in relation
to the front wheel's contact patch. An endo is possible with the weight
below the axle, although not likely because of insufficient traction.
