That sounds like a cool idea.
Do you have a picture of the bars?
I agree, a custom shop would be of the most assistance.
Custom length brake and Clutch cables are common, but you also have the electrics to work on.
I'd suggest doing the electrical work carefully and with patience to make sure it is done right.
Electrical problems (especially the intermittent ones) are a bitch.
Good luck, post pictures...
