Yes, it would be possible. Easy, in fact, given the kind of information 
available on the web and in the sources of the software emulators for 
this machine.

Putting the whole Commodore 64 on one chip would require an FPGA with 
at least 512 Kbits of RAM and those are very expensive. And it would 
also be a waste since these chips have much more logic than I think you 
will need. A better option would be to use a much smaller FPGA and 
external RAM chips.

It would be very fun to make the 6502 core run at 50 MHz or more but I 
doubt that many C64 programs will run except at the original speed. An 
Apple II implementation might be more interesting since business 
programs such as AppleWorks are more likely to run at high speeds. But 
this is just a guess.
