How would you do this in a modern (something like Supernatural) or historical (say Elizabethan) setting. The closest to summoning would be conjuring and the closest to exorcising is dispelling, but neither of these use the Divine skill which would seem the best fit thematically.

Is it worth a separate spell type, something like demonology?

A talent called Demonology that allows those spells to be cast with Divine? It should specifically limit it to daemons. Sounds like a Tier 4

Or just change the spells allowed by each skill to more closely match the setting
