Catasetum weird growth: what next?

I've been growing Catasetum types successfully for a few years now, but have to say this is the first time I've encountered this. Here's a Cycnoches cooperi that is starting its new growth from 2/3 of the way up an existing pseudobulb. There are no new growths emerging at the base of the old bulbs. Just this one. Might it be possible to treat it like a keiki, sever it from the bulb, and pot it on its own once the roots get a bit longer? Meantime, I know from experience you're not supposed to start watering these until the new roots are a few inches long, otherwise you risk rotting the plant. But I'm at a loss how to do that with the roots suspended in the air.

Thanks for the idea. This particular pseudobulb is hanging on precariously at its base, and I had to stake it up last year to keep it from breaking off. So I've also thought about just taking off the whole pseudobulb and laying it horizontally so that the roots on the new growth make contact with the moss.
