Can I save this rootless orchid with velamin?

[milkygato]

Hello everyone, need your expert opinion once again. I have an orchid that suffered bad root rot (I think I overwatered it) so I removed the rotten casing, submerged in kelpmax, repotted in fresh bark, watered once a week with kelpmax. It’s been about a month and a half since and the leaves are still droppy and one of the stem looks like it’s drying up. Interestingly, there are new shoots growing from stem. I took it out of the pot today and I don’t see any new roots yet. Should I continue with just leaving it potted in bark to see if it survives? Should I cut the stems? I was thinking of leaving the velamin submerged in water for now with a plastic bad wrapped around the entire leaf and root area to increase humidity. What are your thoughts on this?

Thank you for your advice in advance!
