Dev boards start a lot cheaper than that. A dev board probably won't do for the universal board though. Probably have to make up a new board.
There's no reason (short of time, cost and programming) that I can see why an FPGA couldn't handle the tasks described above. That doesn't mean it would be easy or cheap. It's on a par with some of the feasibility rants in the '060 upgrade thread.
The Xylo boards in the shop (see link) look pretty cool; USB and an ARM CPU on board as well as the FPGA
