Umm... no, Mel, because if Grant were to build it... well...
It would be the first 486 to run MacOS (and reliably, most likely!)
The DMA controller would be a G3.
All the RAM would be some old Nat Semi SF EEPROMs (and you thought that they
stopped production!  Nope, all the mail's been redirected to Grant's house, in
a feat of 3r337 hax0ring skillz that I h4ve y3t to understand :P)
And his IDE controller?  You guessed it, an AVR with heavily optimized mp3
playing code (oops, wrong AVR)
But, it MIGHT outrun his AVR IDE interface setup =P

P.S. Wow, that was fun... =)
