Love it.

I was kind of thinking about making an accelerator board for the compact Macs, like the Plus and SE. Not that there weren't plenty of those around back in the day, but they're not exactly common now. And it would be fun to add modern goodies to it. If that interests you at all, I'd be happy to help, and I think there would be a much bigger market than for a Portable-specific accelerator. 

Either way, I think the only 68000-family CPU that's still in production is the 68SEC000, which goes up to 20 MHz. Digikey has the 16MHz version for about $15 if you're buying a few at once: http://www.digikey.com/product-detail/en/MC68SEC000AA16/MC68SEC000AA16-ND/954577

Beyond that, if you want 68K family, you'd probably have to use a Coldfire or Dragonball CPU. But I'm not sure those are still available either, and they're different enough that there might be software-level or ROM code incompatibilities.

Maybe you could find a box of old stock 68030's from one of the surplus parts warehouses or through octopart.com
