If it's possible to have multiple DPS classes that do the same thing but look different doing it ("selfish" dps like BLM/SAM, BRD & now DNC buffs/support, etc) then it's possible to give us multiple healers that do the same thing and look different while doing it. They just won't because a majority of players are DPS who pitch a fit at the idea of not being catered to for one expansion.

I've already told my FC that I will no longer be using healer on DF for any content that requires randos. I will only bring it out to support my FC. Random DPS can rot in the queue for all I care.
