EDIT: If I understand you, you are suggesting that you splice into the main IGN circuit currently on the fork neck with a heavy duty relay which would be controlled by the existing RUN/STOP switch on the handlebar (and hard-wiring the RUN/STOP circuit permanently in RUN). So, both the neck switch and the handlebar switch would have to be ON for the bike to run?
I don't see why it wouldn't work, provided you use a heavy relay to splice into the IGN circuit -- the IGN switch carries a LOT of current directly (check out the guage of the wire running to the switch!), so reusing the RUN/STOP circuitry without a high-amp relay wouldn't be a good plan in the long run.
Downside? You would have no fast way to turn the bike OFF if that relay failed. In the stock config, you can turn the bike off via the key OR the RUN/STOP, which gives you a fail-safe way to shut down the machine. Relays on the whole are pretty reliable devices, but being an electro-mechanical device, they DO fail, sometimes in the ON position, and as luck would have it, it would almost certainly choose to fail when you do NOT have the key handy!
