Yes. These aren't like subclass spells which can come from anywhere. Keeping them within their own spell list is a must for this project. I'll update the OP to make that clear.
...oh well, just ignore these suggestions then, i'd already picked most of them out when you posted this and wanted to finish the list anyway.
