I certainly think this is a worthwhile project. The main hurdles for replacing Maxima in Sage are integration, DEs, and limits. If you can get sympy working on top of pynac in Sage that provides a big leg up on getting Maxima replaced. The other project I'd like to see is interoperability of symbolics with polynomials. If I define a polynomial with pynac/Maxima, I'd like to use the polynomial commands (possibly through a conversion) and then convert back. I believe you can convert to a polynomial, but not back.
