What I imagine to be possible or likely is that he will keep being his substitute Shinigami self, now with a complete/real Zanpakuto, maybe having some more Hollow features e.g. in Bankai than before, and having or eventually learning some Quincy techniques like Blut (Vene at least) that he can use consciously at will, and maybe some Hollow-related techniques like Cero, I'd like to see him gain that ability.

I would like to see him gain a new Bankai form similar to Ginjo's after stealing his Fullbring - a Bankai form with prominent Hollow-like features, perhaps with two stripes running down his face across his eyes similar to the mask of his last full Hollow form, maybe even the horns, longer hair, and the ability to use Cero. Maybe even of a color we haven't seen used yet, like a shade of orange with black outlining or black with orange outlining or something.

He is a Shinigami and part Quincy, but gaining the abilities of Resurrección and Letzt Stil - or better, Vollständig as Letzt Stil was a one-time technique like Mugetsu - in addition to his (assumed) quite powerful Shinigami powers and Bankai, I think that would be a bit OP even though he is part Quincy and has some degree of (traces of?) Hollow powers or Reiatsu or whatever mixed with his Shinigami powers.
