I think the only way this album can work is if Beyonce just does the hook on every song. U get that on a Jay Z solo album anyway most the songs have an RnB featured singer doing the hook while Jay Z just handles the rappin. But if it's a proper collab album where Beyonce gonna be singing on verses as well while Jay Z gonna be rappin some verses. It won't work and sound good. Jay Z is a complex technical rhymer a pure technician MC who's style is based on complex world play, complex triple entendres, slick punchlines, technical flows, battle raps, similies, double time rhyming. While Beyonce is an RnB/Pop Singer. The 2 styles do not blend well or sound good together at all. There are other rappers with a different style Beyonce could make good music with. rappers with Jay Z style is not suited to Beyonce at all
