The following is my own opinion and strictly an opinion:
That would do it for me, personally. You have the best of both worlds that way. Honestly, the only reason I would have a yellow belly is for looks as a display animal, but in reality, ball pythons make mediocre display animals because they hide so much. Boa's are much more active and climb and come out more often. To me, a nicaraguan boa is on the same level as a yellowbelly BP cosmetically. But don't let my opinion persuade you if you don't feel 100% about it.

Another way to look at it:
I saw baby Nic Boa's (10"-12") for sale at a show today for $25 (sorry, I can't remember the breeders name). At a price this cheap, you can't go wrong keeping the BP and getting a Boa, yanno?
