Ufc boxing

This is a long shot i get it, but Dana White has been talking about it. It makes sense with new owners trying to make money especially after seeing how a crossover fight did (maymac). What are chances they offer mayweather contract to box in the cage? Could lead to what bellator has with kickboxing but with boxing, kick boxing, they already have ebi on ufc fight pass for bjj. Why not incoroprate stars from all facets for huge ppvs? 

Roger Gracie vs josh Barnett grappling

Gokhan Saki vs Anthony Johnson kickboxing

Anthony Joshua vs Francis Ngannou boxing

lomachenko vs dillashaw mma

What do do you think? Am I too high?
