well if you need a hand moving the battery let me know.
As far as the starter solenoid, I have that strapped to the top of my "relocated" battery. I'm not sure where you could stick it with the battery in the stock position. Possibly under the seat between the frame rails. You could make a metal pan and stash all the wiring up there.
I'm assuming youre ditching the left side cover? There was another member on here that got rid of the airbox but left the battery in the same spot. The name doesnt come to me at the moment. He was from the UK with a blacked out bike...if I think of it I'll PM you.
