If the WO are similar to the AE version I have, you need about 110mm of back focus to make them work.
They seem to be easy/ better to use on SCT systems.
A x2 barlow should push the focus out far enough but at the cost of the added magnification & loss of FOV.
I don't think most Bino viewers work (well) with eyepieces greater than 18mm, so using a barlow will unfortunately give effectively a maximum eyepiece fl of 8mm or so.....
