Tosen gained a so-called Resurreción (don't believe it was an actual Resurreción, more like a psuedo-resurrecion) because Aizen was able to give it to him using the Hogyoku. However, the form was incomplete, gangly, and unsuitable for combat. We haven't seen Visored gaining Resurreción, so like I said, if you want to give Alvin one you are going to have to come up with a very good reason.

As for the contract with his Inner Hollow, yes that does sound very similar to Ichigo, but remember Ichigo just gained control over his Hollow. He never gained a Resurreción.
