Sounds like you have a whole plan worked out but swapping a 6 lug 9.5" in the rear and putting some nice calipers on the front would make it pretty usable with mild tires (33-35") on 6 lug. Maybe figure out some bigger lug studs for the front too.
Nice find, coming across one like that would tempt me for sure.
