Brian, just an idea, from looking at your original pictures again. Since you have so many, I'd be inclined to try mounting a few of those keikis on a totem. Phals grow on the trunks of trees in nature, with their crowns facing down. The flower stems hang gracefully and the flowers face upwards when they are mounted like that. You can hang them on a wall, or just use as a hanging plant.
They will take more misting, and watering that way, though. If you go away, you'd need to put it where a sprinkler or mister would hit it. But it looks like you must be doing a great job of that anyway, given all those healthy roots on the keikis. Biggest problem most people have with Phals is overwatering them, or crown rot from water sitting in the leaves. Mounting essentially makes that impossible.
I use the coco fiber liner for hanging baskets that you can buy at HD or Lowe's and just staple or tie it to a piece of wood - firewood would work, I'd think!
I'm going to get me some of that keiki paste! I love propagating plants.
