Try for a simple and compatible design. I mean, you're talking about
replacing the DRAM's with faster SRAM's. MagerValp just pointed out that
you'd have to physically replace the PLA with a new one that will redirect
the VIC chip to the faster SRAM. And what's all this talk about 8 virtual
C64's? Just try to design a cartridge unit that has a 65816 running from
8-20 MHz, 4-16Mb of RAM, some fast SRAM for the local RAM and ROM's,
rudimentary mirroring, etc.

People would love to have an accellerator for their c64 hobbyist endeavors,
but don't want to spend the $$$ for the SuperCPU. I suspect there'd be a lot
of interest for that reason alone. Unfortunately, it sounds like a simple
design really isn't feasible and that the resulting product will just be as
expensive as a SuperCPU.
I did like Nicholas Coplin's c64 accellerator ideas; He talked about using a
Pentium-class computer running a 6502 (65816?) clone via software based
emulation and piping the input/output streams to the c64. Conceivably, the
faster the Pentium computer is, the faster the accellerator could run, etc.
Enjoy.
