You and anyone else who has done this deserves an award for
perseverence. It's a bit tricky, since a fully functional
subclass requires the use of the CULL, DRAW and ISECT callbacks
in which not all of the necessary traverser state is queriable.

However, we are trying to make Performer more extensible.
The C++ API with 2.0 is one more step in that direction.
