Probably... maybe.... not sure.
Every now and again I get the inclination to go back to my Paladin as he's my former main, has all my vanity items, mog sets, exalted reps... basically everything of note I've collected since Vanilla, but I do really enjoy the Monk, and the Legendary cloak has stopped me main changing off him this late in the expansion.
That being said, I *might* go back to the Pally purely for OCD reasons. I don't know why, but it bothers me that my current main doesn't have all Quests completed and all reps at exalted. Every now and again, I try to re-do that stuff on the Monk, then my eyes bleed and I give up. BOA achievements are the only reason I was able to bring myself to re-roll, but even that might not be enough.
