Quick NPCs question

[Nanoha Takamachi]

Okay so, the rules on NPC submission/suggestion implies they have to be original characters, yes?

Are we allowed to submit a suggestion for an existing character to be an NPC, provided we get clearance for that? I have three NPCs in mind who are either very, very, obscure, from a novel and inherently wouldn't work as a person-written Prime, or just unlikely to get chosen as a person-written Prime.

If that is kosher, in theory, then I'll do actual write ups for them and see what Omni/Ganon think. Just checking ahead so I don't spend time on something I couldn't do anyway.

I'm looking for original NPCs but if you've got a good idea I'll still listen. However, if they inherently wouldn't work as a person-written Prime, they probably wouldn't work as an NPC either. The best idea is probably to give me the idea before you potentially waste time writing them up.
