Hmm... If I had to pick using only the current classes:

PLD - PGL (Secondwind and Featherfoot primarily)
WAR - LNC (Lifesurge primarily also Feint)
MNK - ARC (Raging primarily)
DRG - ARC (Raging primarily)
BRD - ACN (Resurrection, Eye for an Eye, Virus)
BLM - LNC (Blood for Blood and Lifesurge)
SMN - PGL (Interal Release)
SCH - ARC (Raging primarily also Quelling)
WHM - ARC (Quelling primarily)

Would some of these be broken as all else? I'm sure haha. But it would be fun/nice to have these dream abilities. Of course there could be even more fun abilities down the line from other classes.
