I heard rumors that this was just a simplified and proprietary PCI slot. It made me wonder if the slot could be converted to a regular PCI slot.

Despite being PCI Express the current PC hardware interface trend, I would certainly go the older PCI route, as there is already an available Amiga open source implementation (the Prometheus) which could be used as a basis for such a project.
PCI is plenty of fast for the old Amiga hardware and probably even FPGA CPU motherboards. Existing drivers for PCI are an advantage as are cheap PCI cards.

It may be possible for an FPGA buster to be transparently optimized for PCI thus improving the performance for PCI. This could help with gfx bus speeds of gfx cards. Changing timings very much on Zorro cards is going to be less compatible even if Zorro III could be enhanced while being in spec. Some of the hardware was never tested with a faster spec.
