Having done thousands of copy negatives of prints of all sizes, the best set up was using a view camera on a tripod, holding the print on a metal board with magnetic strips, and studio stobes set at 45 degree angles.
Most of the time, would use a roll film back making 6x9 negatives, occasionally a 4x5 negative if restoration was needed.
Your Mamaya 645 should work fine. I always used a slow film.
