I think the hydroponic rocks will do better than the bark. You will not have a decaying issue with the rocks.
Phrags should do fine in that they usually like more moisture than Paphs.
You might have a slight problem in that hydroponic rock is light and can float out. (You want it this light since it makes it easy for roots to grow through it.) You probably should have a pot with the top slightly out of the water. You might experiment with a pot or basket with a liner that is thin enough to not be noticeable. With the liner coming over the top.
There are lots of possibilities. You might make a bag out of a thin mesh and when putting it in the basket you could hide it with something else.
Let us know what works, I would be interested.
