But my counterpoint would be that the moss will go sour, it will become acidic and the roots will begin to die.
When you grow orchids, repotting just becomes part of the hobby.
You have options from potting them, putting them back into sphagnum, putting it in a basket or on a mount. It becomes a matter of just how comfortable you are with whatever method use choose.
We all face fear and uncertainty with our initial attempts at repotting. But with every one you do, your confidence should grow. My first dozen or so were frightening, my last 1,000, not so much.
You can do it!!!!!
