The squad druid is also responsible for some of the BFC (and three other things) and there are other workarounds for communication. But the arcane-only buffs, illusions and Floating Disks can't be replaced. The squad is greatly weakened if either of the full casters are replaced - it simply cannot do all the tasks that circumstances in the field might demand of it.
