I'd imagine they'd just pick the Duelist style since that's the designated beginner class.If X gets ported, Cross could survive with the continue save file trick, but they’ve still got too many weapons (and it doesn’t behave like Inkling/Octoling, weapons are tied to skill sets in X)...
Actually, they have 7 personalities, one for each voice actor. Even the basic one has cool lines like "Fate dealt us these cards, so we have to play them" (at least, the male one says this). You must just be remembering the fact that they have no lines in cutscenes (likely for budgetary reasons)....and are too much of a blank slate personality wise. Even Corrin and Byleth have personalities...
I don't think Cross should be the pick, but they are realizable, personality and all.
