I have the Nikkor-SW 90mm f8, which is a bit smaller than your lens, but also in a Copal 0. It's a tight fit inside the smallish bellows of the GV-II and you won't be able to get much movement. It's a shame when you have a lens that can cover 5x7.
My GV-II came with the Optar 90mm f6.8 in a recessed board. It's a quite respectable lens although won't cover much more than 4x5 so movements end up a bit limited. I've also used a 90mm f6.8 Angulon, which is little different from the Optar.
I think I have a spare recessed board, but I believe it's drilled for a Copal 1. I'll check later.
