Has anybody tried to engineer a replacement for the Tube ULA?

I was playing with an XMOS XS1-G4 development kit over Christmas. The
XS1-G4 is a cheap 400MHz quad-core microprocessor with extremely fancy
IO facilities that's designed for doing FPGA-like stuff. The thought
occurred at the time that it probably wouldn't be too hard to knock up
an XS1 coprocessor for the BBC, with the chip emulating the ULA (and any
external CPU you like) in software...
