Think of the Akiko c2p as little more than a buffer, the CPU writes the chunky data to the buffer from the chip ram, and then reads it back to the chip ram in a different format... As Alexh has pointed out an 020 with some fast ram and an optimized c2p fast ram to chip ram copy routine can easily outpace the much cheaper Akiko approach :-)
Remember, Akiko's main role was really CDRom stuff.
Thinking about Commodore would only have needed to add two new modes to Lisa to have remained competitive at the time... A 256 colour packed pixel 640*256 (200 for NTSC) mode and a 256 colour packed pixel VGA mode (640*480)... That would have bought the Amiga at least two more years!!!!
