I personally would rather see a PPC accelerator so you can either run MorphOS or OS4 on your classic amiga. The phase5/DEC ppc cards are rare and expensive, and I think you could probably sell a more modern PPC accelerator card to a reasonable number of classic Amiga users.
I'd say a PPC accelerator with a G3 on it, a local ram socket and anything else that fits (like a video chip). Would be very nice...
