Old Raf with a new RAF question.

Ok so here is the deal.

I want to level a rogue but I realize it will take way longer then I want if I don't RAF it so here is what I want to do and tell me if you think this will work.

Main Account - Rogue
RAF Account (From main) - Priest

So I'm thinking of doing what someone suggested and just RAF one account off my main for a vanilla wow. I am thinking just a priest to keep healing the rogue. My other thought is I would quest boost and occasionally instance boost with 3 elemental shammies in tow.

Would this work if I grouped the following (Leveling Rogue, Leveling Priest, and 3 elemental shamans following)? I'm think this would work because the main account and RAF account are seperate from the other 3 boosting accounts, but I just want to be sure.

That sounds like it will work perfectly.
