Maybe the RAM of the "addon coprocessor" is not upgradeable, but the
addon board itself can be replaced with another one (one with more RAM).

Yes, but that’s a lot more expensive.

I had this crazy idea of putting cpus right on the ram. So, if you add
more memory to your system you automatically get more cpu's... Think
NUMA for a moment... ;^)

Can software use the extra CPUs ?
Also note: DRAMs are made on P-Channel process (leakage) with only a few
layer of metal while CPUs are based on a N-Channel process (speed) with
many layers of metal.
Bus interconnects are not setup to take a CPU cache miss from one
DRAM to a different DRAM on behalf of its contained CPU(s).
