Even if she didn't manage to fix her dantian to become a martial artist, if this vision allows her to become a peerless healer, she would still be highly respected and sought-after, perhaps far more so than a random expert martial artist. It might be a more valuable personal power than being able to cultivate. And yeah, once good enough, she might even be able to fix her dantian. Qi could be necessary for more advanced healing techniques, anyway.
