If you really are serious about this. Look at the VCO-3A 
again. I used it in the MM and Mini4. After considering 
your idea a little more, I think this might actually be 
a solution. 

Temp-stability is good. It would still require at least a tempco 
and maybe 3046s if you were going to gang them up.

This is (no offence...really) a pretty nutty idea. Having only 12/16 
CEM3340s in a poly they used a cpu to keep 'em almost in tune, some 
of the time, and those were Curtis chips.
