I think he might rock an updated version of that green wraparound thing.
He surely would.
I don't think Pine had an issue with the gold uniform. JJ decided from an artistic perspective that he wanted to wait until then end of the film for Pine to wear the uniform. I'm sure in the next movie he will be wearing the standard uniform for most of it.
That's pretty much my take on it. Mind you, gold is a difficult colour to wear - it suited Shatner IMO but not that many others (I reckon that's why they changed command to red for TNG), I don't think it's Pine's best colour though he's goodlooking enough to get away with it.
The green wrap gets my vote.
