Sure, you probably could, but would it be worthwhile?  You'd have to change
the clock crystal and the CPU.  In fact, the clock crystal would have to be
*slowed down* from 50 MHz to 33 MHz.  The addition of the DX2 would make the
CPU behave like a 66 MHz machine (instead of 50), but the rest of the machine
would act like a 33 MHz machine (again instead of 50).  If you are using
*very* CPU-intensive applications, this might help.  If you're doing things
which requires mostly disk, video or memory, a DX2/66 might be almost a
downgrade from a DX/50.  Most people I know who have seen both (I've never
seen a DX2/66) say there's virtually no difference in performance.

Another requirement for a DX2/66 is *lots* of external cache--without at
least 256K, the DX/50 would probably be faster because the DX2/66 would
encounter a lot of wait states without it.  Many people even advocate a 512K
cache.  Again, I haven't seen it, so I'm relying on opinions of people who
know more about the DX2/66 than I do.
