Integration had a similar theme, maybe look at some of the nameing ideas in it?
Tesserayial (Aureal)
Kara'shivial (Xivilai)
Kenerial (Mazken)
Turumin ( Daedra Seducer)
Teshekru (DS)
Thoseare some basics I can remember offthetop of my head. bg knows a lot about lore, and I'm not sure how he made up the names but they should be fairly apropriate naming conventions.
Some of the older games like BattleSpire and Daggerfall have Daedra NPCs too, if you want more direct lore names.
EDIT: Bah, I really have to get out of the habit reading the first post and then skimming the rest. Anyway, bg might be able to help you, you could also look into some of the in game books (I believe Daggerfall had the most, andthere was at least one real novel), or maybe... check out the http://www.imperial-library.info/, posting this on the lore forum mighthelp too.
Definitely some good ideas there. I do remember seeing the names of a few Seducers while skimming the Battlespire plot from Imperial Library, and the lore forum might have something to say as well. I actually contacted bg this morning, via message, asking for permission to include elements of Integration in my mod, and for advice on naming daedra. I know he's not very active on these forums, but I am hoping to be able to call my mod a sequel to Integration, and include cameos if possible. Poking around on uesp's Aureal and Mazken pages, I was able to find their lists of ingame members of those races. I'll likely compile as many lists as I can, using the books referenced at the Imperial Library, any records from previous games, and bg's work.
If anyone else has any tips, though, I'm still open to suggestions.
