Steve has famously ridden a full black bike back in 1998 when he also took his first win at Snoqualmie Pass, so I'd stick to that theme, trying to build a bike as close to that. BUT!
I think an original polished frame is too bad to paint black, so I'd try to swap with one that is already black. It's just a suggestion. Maybe there are people who'd like a polished one and you don't care what color it is, since you're gonna paint your replica anyway.
Cheers,
