Your ideas are possibly better just because you already have a chance of building them if they're that close to existing analog schemes. I'd try them first to get a feel for the whole thing.
Far as reprogrammable, type in what I told you into Google: Field-Programmable, Analog Arrays (FPAA's). Or reconfigurable analog. You'll get companies and CompSci. Also remember that analog works best/easiest on oldest process nodes. That combined with multi-project wafers can get your ASIC prototypes down to thousands of dollars rather than tens to hundreds. Middle ground company is a structured ASIC that's basically like a FPGA programmed with 1-2 masks at fab time. Triad Sdmiconductor does that for digital+analog with claimed $400k per design with few weeks turn around. Idk if their analog cells are suitable, though.
Also, for good measure you might enjoy at least looking at the last general-purpose (programmable), analog computer:
