The MT/OT sub-role split doesn't work due to the nature of fights being designed with tank swaps in mind as all tanks end up doing MT and OT duties. If their were no tank swaps and OTs were expected to spend a fair amount of time out of melee range a 2 melee centric MT/2 ranged centric OT split could work.

Healing on the other hand works better with a separation of duties one healer being proactive (barrier heals) and one healer being reactive (regen/pure heals).
