You should be able to but ZSurf creates some surfaces that have pretty high control point counts in a single surface, it could be possible that you might run into some refinement limits in MoI if they get to a really really high level of density.

So if you are doing something really complex using ZSurf's built in wrap around cylinder or sphere could be helpful.
