Yair,Graham, one (expensive) solution is to have 2 adapter plates: 1 attached to the back and 1 attached to the GG, the 1 for the back serves as a bumper so the IR filter os alway recessed a few mm...
You'll have to make some sort of dust cover for it but that should not be too difficult.

Thanks - yes with the Alpa, the back plate, ground glass and lens mounts all have this architecture, including a push on plastic cover. It works well as everything is the same size. (I destroyed my sensor/IR actually when I was refitting it to the mount plate while it was on the camera - not the workflow I normally followed alas).
