Well, if you had god-like soldering abilities, you could desolder the PPC601 chip from the PM7500/100 card and put it on the 7100 board. You'd also need to replace one of the resistors on the adjustable voltage regulator and maybe add level-converting buffers to some of the IOs as the PPC601/100 uses some different voltage levels from the PPC601/66 or 80. One thing that makes this more difficult is that Apple hot-glued the CPU down. If you look on the back of the PM7500/100 card you'll see a hole behind the PPC601. Apparently, they squirted hot glue in through this hole or let it escape through that hole as they set the CPU down in the glue.
