Put it simply, if the U12 was such a popular make that we here at antrx were swimming in product from sponsors, building a dedicated track car (drag or street) would be a very feasible option.
Consdering that we aren't, and the funding has to come out of others pockets, it will not work.
IMHO i wouldn't be handing over cash for a "club" project car when i have my own to spend money on and finish.
