This isn't a specific reply to anyone in particular, just an odd thought.

Looking through a copy of Amazing Computing last night, I noticed an add
for a DKB systems MegaChip, chip ram expander for the 2000.  Now the thought
hit me that with the A500's problems in expanding chip ram, this seems to 
be exactly what the 500 needs.

A 1.5 Meg, Chip ram expansion.  - Taking the A500 to 2 meg chip ram.
It seems like it would be an easy expansion to build, and would let A500
users expand to 2 meg chip ram, without having to invalidate service work
by modifying the system board, etc.  It appears that the A2000 chip ram
expansion is little more than a new Agnus, on a daughterboard with a 
meg of memory, and some glue logic.

Is this a crazy idea?  Would there be addressing conflicts that are
unresolvable?  Or could something like this work?  Worse yet, is it
marketable?
