I have the 4" focuser. The 2x converter I was referring to is the one
Pentax sells for use between their lenses and the camera body. I figure,
if it doesn't create any optical problems it would attach quite nicely
as the field flattener has the "rear end" of a Pentax lens built onto
it. All you'd have to do is unhitch the body put in the 2x converter and
hook the body back on.
