Wobbles are not genetic at all to my knowledge and i wouldnt hesitate to breed her. I wouldnt allow her to maternally incubate, but im pretty sure you have a bator anyhow.
I would not hesitate at all to move her into the rack. Also if you get a chance to, posting a video of it would really help. No matter how well you try and explain the severity of it, the wobble could be worse or better than what were picturing in our heads lol.

For comparison, is it as bad as this? Not as bad or worse?:
