Frankly, from your description I'd be wondering whether it *is* time to think
about a 68020 or 030.  Your plans are taking the 68000 farther and farther
from direct control of the bus; it doesn't sound like it would be lots
harder to just switch to one of the better processors.  They are capable
of running on the narrower bus, and apart from being faster in various
other ways, have built-in caches.
