I'm...doubting this. See, I don't think the techniques of a Shinigami and a Quincy can be combined because they are the exact opposite of each other, just like Humans and Hollows. We've seen the powers of a Shinigami and Hollow work in unison(ish) with the Visored, and Ichigo's Shinigami powers are also his inner Hollow (though he considers his Quincy Powers to be part of it as well) so I'm sure that will be reflected in whatever abilities he gains. However, his Quincy powers are currently latent, being activated by the old Zangetsu, and beyond possibly Blut Arterie being activated to increase his attacking power, I don't think his Quincy powers will directly interact with his Shinigami abilities. Also, I get the feeling Vollstandig isn't something that one achieves in 9 days, even if that person is Ichigo, and I don't think Urahara has a cheating device for allowing him to learn it in 3 days like he did with what we thought was his Bankai.

tl;dr Ichigo's Hollow and Shinigami powers will work together because they are intertwined, Quincy powers probably won't aid him beyond activating Blut Vene and Blut Arterie.
