it would be an epic build - the frame vendor I linked to already has experience tying in to Porsche running gear, and the 904 body doesn't look that difficult to graft on. the devil is in the (many) details in something like this, however.
these guys to a g12 body:
DARE UK - Products - G12
and these guys do an xk13 body:
SCF XJ13
Hybrid Mode
