He kind of does that already with the Wyvern as is. The Wyvern themselves allow him to use Albion's moves, like Divide and Reflect. They might also allow use of Half Dimension and maybe even Compression Divider in the future, but I doubt the ladder.

Part of the idea with Issei and Vali is that they are supposed to be opposites, that doesn't really happen if Issei just uses Vali's abilities as well. Him having Divide and Reflect are fine, so I don't think we are going to see anything else.
