One of the lenses I'm considering a Packard for is a Wollensak Verito 7.75".

The lens has a nice flange, but the back element stick out nearly 1 inch past the flange. Won't this protrude into the Packard?

Make a box to mount the lens and shutter. This way the rear element sits in front of the shutter.

That, or mount it on the front of lens.

LOTS AND LOTS of lenses have rear elements that sit beyond the lens flange in back. You just glue together several pieces of wood to make a THICK lensboard.

Actually as Gene said - thick lensboards to the trick. Check out my packard shutter mod in my sig. In the pics you'll see the lenses sit deep in the 3/4 inch wood.

I've seen your mod; at the end of the day, I'll end up with an overized Packard sitting outside. I wonder what having the lens so far out does to tilting.

When you tilt, you'll also need to use some rise/fall to recompose and you'll probably need an extra iteration or two of focus and tilt in this situation, not unlike using a telephoto lens, but it's manageable once you get used to it. If the distortion isn't a problem, then rear tilts are easier with a lens mounted this way.
