I think it'll be ok. I've gotten a ton of pings from people here recently, and even with my rough, unskilled manhandling, breaking off leaves left and right while trying to pot them, they all survived. The existing leaves that are pretty bad off might die, so you can prolly pull those and stick em in the soil to grow plantlets(I got like 14 P. ehlersiae growing that way lol)... And i'd def. put a plastic cup with holes punched in it over the plant to help keep it hydrated while it heals and grows new leaves.
Edit: sorry missed that you already said you had a dome over it.. doh. lol
