If anything, a smaller triac could be used to get the caps charged up, then connect the main wires together (bypassing the triac) for running.

If you still want to go this route, I'd use a small bank of FETs to do the switching. That way, you can keep it in the circuit with minimal losses if you really want to use it while running.
Hey I didn't say it was practical...
