Tried sphag and bag method, what do you guys think?

[Orchid grower]

Hello everyone! I have this Phal that means the world to me and have been trying to save it for over two years now. Over the two years it has on and off done ok.. it never recovered from the root rot of being so tightly packed from when I originally got it. Recently it lost its one only good root so I have finally tried the sphag and bag method. It's been about maybe 3 weeks now. While being in the bag it lost its last large leaf it came with so now only has tiny leaves, it looks like a mini Phal but it's meant to be a large noid. I have posted pics of how it's doing know, 2 new roots and a baby leaf! The green pot inside the ziplock bag is just to help the bag stay up. Any advice on how to proceed would be greatly appreciated!!! How long should I wait to repot? Once reported I would put it on a heat mat. I need to save this plant, please help!! Thanks to everyone in advance!!
