If I wanted to do it right I'd pay a machine shop -- my machinist of choice is skgrimes, there are others -- to make a threaded stepped bushing. A male end to go into the shutter's front tube as the rear of a lens' front cell would, a female end to accept the lens' mounting threads.

If I wanted to do it wrong I'd look for T-mount extension tubes and try to bodge something up that would fit the shutter and accept a T-mount tube and that would fit the rear of the lens and screw into a T-mount tube. I don't know if the adapters needed exist. I've done similar with LTM tubes and custom adapters.
