You can scratch the Capanemia micromera from the list, I didn't realize that it was a micro mini, and will need a terrarium environment to do well. Not the ideal project plant...
Another suggestion is one from the project 2 years ago that never took off. Vanda ampullacea (ex Ascocentrum ampullaceum)
Vanda ampullacea or similar species (V. miniatum).
Vanda miniata I would make this one canditate, with the possibility of getting either of these 2, depending on availability.
Tuberolabium kotoense is also a really nice candidate plant.
Tuberolabium kotoense
Another nice one is Dendrobium unicum
