If you feel that this little one can enjoy sufficient quality of life to continue working with her (and I think only you can answer that question, as you know her), then I'd suggest maybe setting her husbandry up in the same way that folks do if they happen to own one a BP with severe wobble. Hopefully others can chime in with suggestions here, but overall it'll be important to keep her environment as low-stress as possible - so be sensitive about about relative brightness of ambient light she's exposed to, keep her exposure to outside stressors minimal by blacking out three sides of her enclosure, be absolutely sure she isn't overheated (and there is at least tentative evidence to suggest that snakes with severe wobble may do better at somewhat lower ambient temps, but this isn't definitive), and perhaps make sure that her enclosure isn't too tall or that it has enough clutter and cover to ensure that she doesn't have to process a lot of visual height information. Finally, you already know she'll require significant assistance with feeding. Best of luck to you and little Rose - she's a lovely little snake and it breaks my heart knowing that such a wee one has been through so much.
