I voted no although the majority think it can happen, Paul will agree, but I doubt if Connor will agree, he will be advised to just go for UFC and not a boxing match, he is good in MMA and has only fought once on boxing while Jake Paul all matches are in boxing that makes him experienced between the two and besides he has something to settle against Poirier, their last fight ended in a freak accident, so the result is not decisive.
I also voted no, though majority went for yes, first, I must admit that am not really up to date with the happenings in UFC, but based on the story, I personally think Connor is being over confident in himself, he should atleast allow himself heal properly from his leg injury which he sustained from his fight against Dustin Poirier, then like the @aioc said, he should settle with Poirier first, before he proceeds to challenging Paul, usman, whoever.
This is just my personal opinion.
