Hi Rachel - there is a command that is new for v2.5/v3 called Flow which might be able to handle the morphing for you of a uniform revolve.

Check out here for some examples:

I'm still not sure exactly what kind of end result you're looking for though, but if it's something like making the revolved shape follow a path then Flow could work for that - you would draw 2 curves, a line going down the middle of your revolve for the base curve, and then a bendy curve for the target one, then select the revolve and run Transform > Deform > Flow, pick the "down the middle line" at the first prompt in Flow and the bendy one in the second prompt and it will generate deformations like this:
