With flat fenders and adjustable arms... 35s on 2" BB is also doable. Sure, clearances everywhere are tight, and wheel offset, bumpstops, trackbars, and limiting front steering is needed... but if tire size, ground clearance, and offroad capability are the issue... there is NO reason to go to stupidly tall lift for any tire size that can be driven on the road comfortably.
OP, also read up on low center of gravity (LCOG) builds.
and I absolutely second (fourth?) the suggestion that you drive it stock, maybe with better tires in a 30 or 31 height, for a year before you start building.

The technical advice you get from me here is worth exactly what you paid me for it. Warranty issues will be reimbursed at double what you paid me for the advice.
