I personally wouldn't mind a succor shield stack although that should not stack with Adlo, nor 2 Adlos.
Two Scholars basically need to think bit otherwise as they usually would and needs a lot more coordination than two WHM.

Altering Sacred soils + Eos/Selene combo give some nice results. You can also coordinate who'll focus on tanks and the other focuses more on the raid.

It's bit sad though that many of the fairy skills don't stack.
