If she's smart and takes the time to develop real striking skill from good coaches, then possibly so. Her grappling is absolutely world class and she has the looks and charisma to be marketable. Her standup striking is still in the early developmental stages, though. She should spend some time improving that before she tries to hit the MMA big leagues.
Well since she's not even in the ufc that's not even a discussion right now. Sure she's good in jiu jitsu but that doesn't mean she'll do great in mma. Right now she's no where near even being a contender for anything. She's 3-0 against unranked opponents and only finished 1 of those fights. Maybe she'll do amazing maybe she won't but if she wants to do anything she can't make rouseys mistake of not training properly in striking. Maybe she'll do well enough now against the amateurs but if she fights in the ufc she needs more than just jiu jitsu fighters have evolved more these days than when rousey was around. If she goes up against Joanna in the ufc with just jiu jitsu she's going to get badly hurt
Also needs to get her weight cut sorted, her last 2 fights she's missed weight. If she wants to be considered a top fighter she needs to make weight and get it sorted ASAP as it'll get harder the older she gets
