I think your orchid looks so much better, I would be reluctant to repot this soon. But, the bark is way too big so will need more water.
I have a Dendrobium that was a keiki I dropped into a wine glass by my sink until I could repot. It did so well in the wine glass I transferred it to a terracotta pot - I stuck it against the wall in the greenhouse (that's the wettest but still brightest place I have). Its blooming, without any medium, just a pot. But, the blooms are starting to take their toll on the plant. I can't keep it wet enough in winter to make it happy, even though its on bloom stalk #2.
Time will tell if your large chunky bark is a good choice (as time will tell if my medium-less terracotta pot is a good choice). But, I personally would give it time...
