Call me crazy, but wouldn't using the CPU (a 020 or 030 I suppose) instead of
the blitter for speed cause a decrease in the overall speed of the machine?  
i.e., one of the reasons the Amiga seems faster than a similar speed PC or Mac
is because of the support hardware and the parallelism.

Perhaps someone should rewrite the blitter in software so and make the blit
routines "intelligently" decide whether to use the CPU or the blitter chip.
For example:  if CPU is a 030 and CPU traffic is slow, then use the CPU
otherwise use the blitter.
