Clearly that's possible given that today's clock speeds are much higher than
those of any VAX, and you could put caches on-chip as well for additional
points. The difficulty would be to create an accurate enough implementation.
Given the availability of the VAX architecture manual, the odds are better than
they would be for many other processors.
For that matter, by the same reasoning it should be doable (and quite possibly
easier) to build an FPGA Alpha. Is the Alpha architecture manual ("SRM")
online?
