SpookyCash offers both CCBill and Epoch tours, as some affiliates prefer CCBill and some Epoch, so I imagine it would be similarly easy for sponsors to offer a CCBill option and a NATS option.
At a certain point, it becomes maybe too many eggs in the CCBill basket, but there are certainly sponsors I would try throwing a few links up for to test, if I thought it was likely I'd get my dough.
