PC Dawnguard recruit a current vampire?

[Torok]

Will they come recruit me if I'm currently a vampire?

I know this seems like a no brainer, but is it possible?

Even with a mod that makes my character appear human?

 

[Phantom]

You can.

But

Spoiler alert.

You can, TO A POINT. After a few quests you will be tested.

I just want to get to Serana and that's it I'm with the vampires.
