Why not go right ahead and create a vampire dragonhunters guild, which uses guns and lightsabers, are led by Jesus himself and control a power coming from an intergalactical energy field called "the force"? Ohh yeah I forgot that the ancestor of the bloodline should be talad's father of course, as well as the whole guild being some kind of super Ajah haveing power over all Aes Sedai...
Really, ..., I strongly think that even at this state the PS setting is big enough for guilds to base on it, instead of randomly pulling stuff from other settings.
Edit: Yes. I do like to be an ass if it comes down to guilds. Ask Petilence about that.
