I planned to get my A530 running at 50Mhz also, but got discouraged by another, reliable A530 owner who actually completed the mod. The result was unstable A530 so he rolled back to initial 40MHz clock rate.
IMHO, putting MC68030RC50C to run at 40Mhz might decrease working heat dissipation well enough to pass active cooling inside A530 case (just a educated guess).
However, if you want MMU-capable MC68040RC40B, I might help you quickly.
