I think many people would like to see 68K Macintosh Apollo accelerators.
I think that there would be almost no interest in 68K Mac accelerators.
68K Mac production stopped around the same time that Commodore went bankrupt.
Apple still produces Macs.
Most people interested in 20 to 30 year old Macs want to use them as they were. (Only 2 of the models that you listed had color displays!)
Fans of the Amiga, Atari ST and X68000 (strong gaming computers) would likely have the most interest in the Apollo core.
