Here’s a few random thoughts...
The first place I’d start repairing is the floor, since it will be the main structure everything else is built on.
Assuming the left side piece you reinstalled has fairly close edges, you should be able to put doubler plates behind the edges and countersink/dimple the rivet holes, then repair the cut formers/stringers, then add a little “aerodynamic smoothing putty”, and paint.
The right side is going to need major reconstruction, certainly some jigging, the fuselage may have already twisted from the loss of structure.
Since the fuselage will be oriented in an “in-flight” attitude, the rear entrance door will require a ladder for entry, or you could fab a simple fold out airstair from the current door.
I don’t see any need to keep the main spar. It is just a huge obstacle inside the cabin and the stub wings are of no use. This is assuming the floor structure is strong enough to attach to a car frame without using any spar structure.
How is the overall length? Looks a bit long for downtown driving. If you are still going for the B-25 glass nose effect, you could shave 18 inches off the existing nose and still make a decent glazed nose. The rear 3-4 ft serves no useful purpose currently, so I’d cut that off and build a glazed area with a seat.
I’d also have two plexiglass domes on top, with seats attached to ring mounts, so your pax could enjoy an awesome view while on the road, and when you park it on the ramp at airshows (it’s a photo platform for pros, that you rent out) the domes open up and the photogs mount their 800mm lens on the swiveling ring mount and fire away as aircraft race by. They would have ideal shooting positions, 12ft above the crowds. The tail position could also be used as a photo platform, as could the openable upper nose hatch.
You could rig fold down cots from the ceiling, add a porta-potti, mini fridge, etc, so 4 photogs could use it as a camper while at the airshow, to get those shots before and after the crowds.
I’d use it to travel from one airshow to another. Put banners, advertising the airshow, on both sides, and drive around the city to make some advertising $$$ a few days before the show. Then rent out the vehicle to a group of photogs for the show. After this rig becomes a cash cow, start on the next. Perhaps some WIX folks would enjoy spending a week’s vacation driving this rig, and having the best seats possible at a major airshow.
If you will haul 8+ people, and baggage, then a little math to figure the C.G. is in order. Any idea what the current fuselage weight is? Any thoughts on what kind of truck frame to use? and how to keep cooling air over the radiator? Maybe an older diesel, that will run on any kind of trash fuel, since fuel prices are predicted to hit $5+ per gallon this summer.
End of random thoughts.
If I can swing a temp sheet metal job in Houston, I’ll drag my tools over and lend a hand.
