Save rotted Phal with water culture?

[Izzie]

I now have two rescue phals that came rotted except for aerial roots, they've both been in bags with a wet paper towel on a seedling heater while I figure out what to do with them.

Would putting them in water for a while help them out? I'm not saying long term, but at least until some new root nubs start (so I'd be repotting when new roots are starting, which I heard is best?)
