Having a patch modeling toolset is not a "bad" idea. But honestly if you are hoping to make something which handles organic modeling better than subd, i don't think you will achieve it just by using patches. It needs to be something more sophisticated than that if you are to overcome the limitations of working in Nurbs. TSplines is a huge improvement for organic Nurbs, and the poly-Nurbs conversion is awesome. I've used it on a few projects that we are now in process of making the injection moulds. But admittedly there is no modeling toolset (coming in version 2!) which compares to the ease and speed of using subd. However TS for Rhino does have a very nice tool (called tsSkin) that allows the input of a minimal set of curves and can output a smoothed solid model from it. you can define very complex forms with very few Nurbs curves. It's a fresh approach to Nurbs modeling. And i think new concepts like this are needed to make Nurbs a viable organic modeling solution...
