I can make that for you (at least the extender harness - you would have to accommodate the mechanical relo of the switch yourself - the accessory socket location on left side might be good option)
well yeah - you just go full KeyLess
Interestingly I actually supplied a Key-Less kit to a NY Sherriff for his active-duty Police Scooter for similar reason - it was really awkward to reach the key-switch with his radio gear mounted between the bars and he contacted me after seeing one of my YouTube videos.
Yes, the connectors are different on early models, changed about '08
