If you could find a kit I think the ignition would need attention. Most/all electronic systems let the engine turn over at least once before firing to counter kick back. With a pedal it's got to fire first time, the old Crane systems could be switched between kick and electric. I don't know if the fuel injection would cope, a bit of suck it and see perhaps. Does the clutch need to be held in at start up and the side stand be up? Most bikes with kickers need a bit of priming before a cold start, is that possible with a injection system?
Just had a wander round google, W&W do a kit by Cannonball for Evo's and Twin Cams but they do suggest an accessory ignition system.
Good luck.
