Have you looked at Bernd Paysan's b16?  It seems more resource efficient
than e.g. a RISC-V softcore could possibly be.

I don't know how to identify the package from the photo on the above
page, but the part has 72kbit of block ram, 1152 LUT-4's, 864
flip-flops, 96k of flash, and from the board price, the part itself must
be pretty cheap.

Doc page here, but no idea what dev tools are needed:
