I love the idea of a 4BT Jeep! If you are going to ditch the factory heater box I say cut the firewall and re-make it with sheet metal. For some real ghetto-fab if you are in a cold climate, run the exhaust pipe through the firewall for your heat.
The YJ you are working with is fairly basic, how about stretching the nose to get the engine out of the firewall? A little more wheel base would be good for the Jeep anyway. Add 10 or 12 inches to the frame, build some flat fenders out of 1/8" plate and fab up the hood to fit. I think the hood would be the difficult part. Your center of gravity would suffer but with the longer nose you could raise the engine and trans up to get out of the axle. This is going to kill your driveshaft angles when you lift it.
I say ditch the factory skid plate and build a cross member that bolts in between the frame rails. I've never seen a 4X4 bread truck so I assume you are going to either swap out the trans or run a divorced Xfer case. If you go the divorced route you will need another cross member for it.
Another option would be to Baja the thing and mount the radiator on the roll bar/cage with an electric fan and move the engine forward to the grill. You can also raise it up and either run no hood or make a giant cowl hood for it.
Score a couple of full width 1 ton axles when it is time to swap. You may be surprised how well the tiny Dana 30/35 holds up if you are easy on the throttle.
I've burnt out on my Jeep, it has been nearly a year since I've turned the key on it. Your post got me excited again, thanks. I'm full of opinions, just ask me.
Good call on posting your Cummins in a Jeep swap on the Powerstroke forum, I think the guys on the other forums like boys anyway. They wouldn't get it.
