An adjustable clock would make things interesting.  

Well, the easiest approach IMO is to modify an emulator first.  Find an open-sourced one, do some modifications with the timings and see how it behaves on a modern PC...

Of course not.  The C64 is a fine tuned piece of machinery.  That's why I suggested that he try it with an emulator first so he can see the consequences

I guess, theoretically, if you *only* accellerate the CPU (say, you end up with a 100MHz 6510) you will probably be able to do _some_ things, but I suppose you can forget about games and demos that rely very much on the instruction timing.
