Personally, I'd just have the Rogue stick to a Sub build, and both attack the same target. Could be a healer, could be a DPS, I'd probably attack healers if it's a Resto Shaman or a Holy Paladin, and I'd attack a DPS if it's anything else. Holy Priest Mass Dispel means Mages are easy kill targets, keep that in mind.
But really, I think if both DPS attack the same target that would help a lot. Splitting damage just won't work against any half decent team, it's really not hard to heal through damage when it's split on two targets like that. You could probably get about 1900-2000 doing it, but don't expect more than that. Priest/Rogue/Monk or Warrior isn't a strong comp, and it's easily countered. You can definitely break 1800, and definitely break 1900, but don't expect to get Glad, or even really Duelist, running that comp. No matter what you do, that's probably not going to happen.
