I think T-splines are set up with more the opposite way as the idea - that you would start something in T-splines and then convert from the T-spline to a regular NURBS surface for doing things like booleans, etc...

T-splines does have a mechanism to convert an untrimmed NURBS surface into a T-spline, it looks like you use the tsConvert command to do that.

But only a full surface can be converted like that, I think things like trim curves or booleaned away areas will be ignored.
