Hello knowledgeable and friendly cohorts!

Quick question, I will try to be succinct as possible. After picking up a set of three syblings unexpectedly, my Coil team is now comprised of

PLD
PLD
WHM
SCH
BLM
BLM
SMN
BRD

I feel like this is bad, lol. Question 1: Is Coil doable with that composition considering the fact that we have low melee dps and we double up on two classes for LB?

Alternatively, I am willing to switch from my i80 PLD to a MNK, and I can get the BLM_01 to switch to WAR, giving me

WAR
PLD
WHM
SCH
MNK
SMN
BLM
BRD

Which I feel is a great Coil team. Is it worth the work for me to switch? I have a MNK @ 21, but a spare Relic oil, 2k philo, and 1200 myth banked, plus all of the dps DL accessories in my bags - so he will be pretty much insta-geared at level 50.

That you very very much for your input in advance, not to be rude but I would appreciate serious input from T4+ Coil raiders, as that's the only portion I'm worried about.
