Vali doesn't like to be ordered around, so there is a good chance he might revolt from Rias and annihilate the entire Rias's team in the process. The fight will be...well boring, Vali is a power house, few can stand against him. And the harem will be nonexistant, Vali is a battle freak unlike issei so you can guess what happens next.

Anyway, it would be better if you ask these kind of things in Talk About What You Want 3 Blog provided by the admins here. Surely by doing that you will get more replies than this.
