A friend of mine cut up her Kinesis Advantage to put a big trackball right in the middle. (There's enough space in the housing, especially if you are not afraid to cut and move the circuit board.)
A similar position might work for you?
I use a standing desk to be in a similar (but upright) position, because sitting is also bad for me.
