DC, those look pretty rough but keep maintaining them as best you can. The central axis area is where the new growth comes from and not sure you have much left to start anything. Though orchids are resilient and they may surprise me!
Here's my very limited experience with the ghost:
I purchased mine in March, before the world started melting down. He was mounted on cork and was told if kept in warm and humid conditions it would be fine. I kept it warm and humid in my mini greenhouse indoor grow area and it really didn't do much. I misted twice a day in the AM and PM, added some Spanish moss for extra moisture holding power and waited.
Around the end of May I noticed some action! A new root tip was poking out of the axis, OMG! I kept up what I was doing and things were looking good.
Except I decided to put it outside when it was raining and warm. I didn't have a way to hold up the mount so I just leaned against a pot. It fell over and there was a cavity in the cork that pooled water and by the next day the plant had drowned. 😫😲🤬
I was pretty upset with myself, should have left it inside where it was doing well but couldn't leave well enough alone. I was mad and decided to check out eBay. There was a very reasonable flask of dendros available that I decided to pull the trigger on.
Plants needed to be deflasked ASAP when I got them. Took me a few days as I was traveling for work but I did as soon as I could. I got a lot of very nice plants, a few bigger than the one I had previously purchased!
I have put them in the humid growspace. I'd say I have a dozen that are close to mountable size and another dozen that are gonna be major projects. This MN dude is doing his best to try and succeed with the FLA ghosts on the second try!
