...take the third break light wire connecting it in the spoiler with a LED light bar (full length maybe...
Personally, if I were going to move the CHMSL, I'd probably not even bother putting it back on, or if I did, have something integrated into the spoiler. Not sure of the electrical part, but on 4th gens, the bulb blowing out on the light would affect cruise control for whatever reason, so maybe an appropriate resistor in its place and hidden perhaps....just thinking out loud.
