Actually I've had several people be successful at doing this, if the base form is easy to define with NURBS but you want to apply some small relief work or other small details on to it, it can work well to combine things in this way.

Here is one previous example:

As far as I have heard it is not so important to get quads in ZBrush as it is to have polygons that are of a more uniform size and even distribution.

Of course normally with output from subdivision surface modelers, they will be all quad output, but as far as I can tell the good thing about that kind of output for displacement is not that they are quads but rather that the quads are all of a nice even size and don't have things like one large polygon directly adjacent to a smaller sized one.

If you use export settings from MoI as described here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=1549.4

that should generally help to get that kind of even distribution and sizing as well.


ZBrush also does not handle N-gons properly, so make sure to export with Output: Quads & Triangles instead of N-gons.
