Possibly... But the 6532 is not a mixed signal chip like the SID so it could be done in one of those programmable logic devices and be a 100% replacement. From what I could find the FPGA2600 project does have a VHDL core for the 6532. I don't know if it's complete since the 2600 didn't use all the features of the chip (no IRQs).
