Yes it is very possible, since the only setup i have done this BCNM with is DRG/WHM DRG/WHM PLD/WAR.
Yag Drink each. (Preferably 2)
The fight itself is very easy untill around 90% when he starts to hit like a truck and spams TP moves like theres no tomorrow.
What we do is have the DRG's Hold TP just before we get to that 90% mark, then after it we unleash 2 Penta's that will knock off a chunk while the PLD Sentinals, then both DRG's should be spamming Healing Breath while the PLD is using some of thier Hi-Pots.
It can get pretty scary if you get unlucky and he decides to spam that Aoe move and someones Wyvern dies, but you should be able to ride it out.
