I like the idea of re-voicing the poly. But how much would this cost?
I wish we had 8 VCF's to use like a DW8000, that bottleneck of the Poly800 usually causes me to treat it as a monosynth.
If you eliminate the voice chip, couldnt you just use the CPU replacement to also do the work of a new TG and patch it's audio out into the VCA's and VCF on the filter chip?
