Please help small to big bolt pattern

I like the wheels, they look sweet. They just won't fit with out a narrowed rear and custom axles.
I'd have to take an inch off each tube and axle in theroy? Does this also affect spring/shock/perch?Or cut and dry shorten reat and custom axles?

I love these wheels and would willing to go through a little extra effort. I plan on dropping the rear during this project anyways and buying axles.

Sorry to keep picking your brain.
