It'd definately be a blend, I think I'd misunderstood Darknemo's point, it may or may not be more like Inner Moka, but either way it'd definately combine the key traits of both, now whether that results in it being more like Inner Moka with a dash of Outer, the other way round, or a 'hotel blend' of the two, we have yet to see.
That said I do think she would be likely to LOOK closer to Inner Moka, because if anything she's going to get more powerful, and Inner Moka looks a bit more vampiric (lean, hard, presumably better looking/more outworldly in her looks, more prominent fangs and inhuman eyes, silver hair, traits also exhibited by Tsukune's more vampiric form...).
Jeez so many coffee jokes possible...
