^^^^ Oh dear. None of that makes any sense at all.
I'd simply award each rider who participated, not the whole team automatically, a rainbow jersey to wear only in TTTs. I imagine they wouldn't want such jerseys to be scattered throughout the teams if some riders left the team, so they could always say that they'd get to wear it only if they stay with the winning team. That would seem simplest to me.
