has anyone added a steering wheel with switches to a Dynamic?
is there a loom present and is retrofitting the 100hp wheel an easy possibility?
Anyone got a 100hp wheel they are not using?!

I guess you could make an estimation on the loom by pulling the head unit out and see if wiring (for controls) is plugged into the back of the head unit.

I'm rather attached to my 100hp steering wheel. Sorry.

presuming its one of the coloured mini iso blocks at the back, yes - there are wires in the 2 possible candidates...
