David,
Not at the moment.
At some time in the reasonably near future I would like a 6mm and an 8mm long eye-relief planetary eyepiece. Burgess are going to do an 8mm but it's not ready yet and the 6mm is still on "garage sale" and has been for a long time.
I wish Pentax made a 6mm and 8mm XW but they dont. Certainly the 8.5mm Pentax XF is a likely candidate in the very near future and the 14mm XW in the 2.5X Powermate gives me 5.6mm anyway.
