I also shoot with a 4x5 field camera and so have a bunch of shuttered large format lenses. They are mounted on Linhof boards. The longest Hasselblad lens I have is 150mm. For the 4x5 I have a nice Nikkor 210mm and a Fujinon 300mm (telephoto design). I wonder if anyone has any experience with trying to adapt such lenses for use with their Hasselblads. I think there is actually a bellows adapter available for some other medium format cameras, but as far as I know not for Hasselblad.
