You can run an even simpler momentary contact on-off keyed switch for the start function, along with the ignition switches. That happens to be how they do it in the RV-12s, and that's what I did too. In fact I used the same compact, light weight switch that the RV uses too... pretty much like what is used on many alarm systems. The 2 ignition toggle switches are completely separate from that start switch. Which ever you use, you want to be sure to use an arc-suppressing diode on the start solenoid/contactor coil circuit to protect the contacts in the start switch from a possible large back emf pulse created when the coil is de-energized and the magnetic field collapses.
