What are my chances?

It's a pink emersonii which lost all it's roots and almost all the leaves apart from what you see.
Will it survive?
Being such a rare thing, I might as well try. Things can't get too much worse.
Sphag and bag....

That one looks good for a try applying IBA. need to get a root growing asap.

I mean it does have an eye but will be tough. Typically lose a leaf or two on a case like that before it gets going again so your margin of error is small

But it will probably be a decade before next blooming if you’re lucky

I did soak in the base in very dilute IBA/NAA for about 4 hours before putting it the bag.

About 200 to 1 against, I'd say. If you weren't a good grower, I'd have said 1000 to 1.

I put it at more like 204.2 to 1.

The chance is very slim, but you have nothing to lose at this point. Give it a try if you have the patience.
