Since doing dungeons/scenarios now increase a rep of your choice. Should Blizz allow you to champion old reps from classic-cata. Give you more reasons to run dungeons/ scenarios to help with que times, finish reps you may not have finished in the past for your achievements, and even open up more rep gear transmogs without causing any negative side effects I wouldn't think. What do ya'll think?
Like it doesn't need to be very efficient. But if players had other incentives to run dungeons if done with current content, then it would help que times is what i'm looking at. Just an alternative really.
@ this idea in general: No, because the reps are there and for the most part aren't gated/dictated by daily quests. There are the reps from MC and AQ40, though, and while they take time, they don't make and break your toon for current content.
