Unless you were getting a ballad, that's essentially 2000 MP mid combat, don't think you would be able to pull that off unless you definitely Energy Drained a couple times..
If I was gonna attempt this, I would probably start with Ifrit and do a basic opener. When hes getting to about 88-89 percent -> SC Garuda, Raging Strikes, INT Pot Dots + contagion and shadow flare on boss.
Miasma 2 then bane off boss, use Aerial slash on boss then re-target garuda. Rouse , Spur, Enkindle the boss asap.spam Bliz 2 alil.
Keep Garuda up through to the next set( Do not use single target Miasma 2 in this fight even if contagion is up for the sake of saving MP) and try to set it up the same way. You wont have Raging Strikes or Pot here immediately but you should refresh your DoTs somewhere in there. If you kill the first 4 mobs before the last 2 spawn, then save Raging Int Pots for DoTs there and hopefully be able to put buffed DoTs on the boss. Switch to Ifrit afterwards. for the rest of the fight. You will probably with most 135/130 gear hit around....570+ by the end assuming your other DPS are pushing the fight fast.
At the same time however this fight doesn't really benefit SMN class when this strat is involved I would imagine, as AoEs from everyone are going out in mass so, I don't see us doing insanely high numbers like some of the other classes cause well it would be dying just that fast.
