sii ------- whether this one makes it or not --- and of course I hope it still has a chance -- it is great that you put in effort to try keep this one going.
If you do have some small to medium pieces bark, you could still try pot this one up in a relatively large - good drainage pot. This one might not make it, but might as well try, since it still has a couple of leaves or so.
I grow some paphs, and I can say that in my tropical conditions, the paphs generally have moisture in the pot - most of the time ----- but occasionally, the potting media inside the pot does get a bit dry, but nothing happens to my paphs. In fact, they still grow leaves, and my big paph grows fairly long and wide leaves ------- and even grows off-shoots (new growths).
If you can view youtube, I recently made a video only to show what I do when I water my orchids ----- in general that is.
If you're interested ----- and if you want to take a quick look at the video ---- and jump right to time
20 mins 38 seconds, you will see that I don't even put water near the stem of my big paph, which is a Paph. Saint Swithin 'Jill'.

Each grower will eventually know more or less how much water should be applied, under the circumstances (eg. media, humidity, temperature etc) ----- just as you'll come up with your system.
For your paph ...... just review (run through for yourself again later) lighting conditions, temperature range, humidity etc. If you can maintain some good growing conditions ------ then definitely try again.
Everybody had to begin and start somewhere.
Anyway - your orchid still has leaves ----- so might as well pot it and give it any chance it still might have to grow a root etc (regardless of what happens). Because you had started growing a paph ----- you're in the paph 'club' already.
