Boost on an already 70 Character

This may have already been asked, but I'll throw it out there...

I'm coming back to DF after stopping shortly after launch, and I'm way behind. The enhanced 70 boost has the rep catch-up and the gear...but I want it all on my main (has all rep from every other expansion maxed), which apparently isn't possible.

Is there some workaround or alternative option for this? I just want to start knocking quests and basic stuff out prior to the next expac.

Thank you much!
