How about Ascocentrum miniatum (Vanda miniata) or Ascocentrum ampullaceum (Vanda ampullacea)? Possibly also Schoenorchis fragrans or Schoenorchis tixieri? Trichoglottis pusilla? Light might be a little on the high side for these, but they might be able to tolerate it.
Also, some of the Sophronitis might be able to handle the light - like S. cernua or S. mantiqueirae (I grow these pretty bright)
