Not a rock person but would the theoretical carbon planets not have significantly different rocks?

Yeah, but I would say that falls into the last paragraph category, i.e., as already stated, if the bulk composition of the starting solar nebula / protoplanetary disk is significantly different than our own, then the possibility of exotic rocks gets much more likely.
