I'm sure someone could make custom wheel adapters.The 3100 front axle will bolt in, and shouldn't be that hard to find, but it's 6 lug not 5, to which you could adapt passenger car 5 lug hubs and drums or better yet, fit one of the 5 lug disc brake kits to the 3100 axle.
You load carrying capacity has already been compromised by the rear axle switch.
