Vampire Aliens? Supernatural hybrids? [answered]

Well, you can't create them as both, and apparently they can't be born hybrid, but what about this:

What if a vampire sim had a sudden thirst for a more exotic drink? Eh? What then?

Or is alien bl- er, plasma not healthy for them? (Which could make perfect sense; different chemicals in the blood.)

Still. Someone with a vampire and access to an alien should test this.
