Another reason not to use the bed sides for support: If you change trucks down the road you don't have to modify the camper to match.

If your A-Liner is one of the smaller ones, you could remove the axels, hitch, etc. and build a basement frame underneath then mount it like a camper.
If you wanted to keep the option of using it as a trailer, you could modify the a-frame tongue section so it's removable and do something similar with the axel. I had a car hauler with a removable tongue so I could store it in my garage. The tongue removed right at the front of the deck. The tongue was made of 3" OD square tube and there were two 3" ID receivers on the front of the trailer.

For your idea of starting with a ladder rack and building around it, I did that a bit over a year ago. I've camped in it about a dozen times. I made the front, sides, rear, and top all removeable so I could use it as an open truck when needed.
I'd post pictures, but I don't use any photo sharing sites. If you want to them, send me a PM and I'll send you a OneDrive link.

It's a bit more than 2 - 1x6s on a standard (not popup) camper overhead, but @mkirsch's recommendation is a good place to start, to design it. Similar design on your ladder rack, if it has a cab overhang. Need relatively stiff sides/cantilevered "joists" that run fore/aft with enough anchorage back in the main camper side wall.

Couple other comments. Reason not to bear on bed sides AND bed floor simultaneously, it'll never be perfect and at some point, either the bed side or the floor will be holding all the weight. Not to mention stability and stress on the bedsides if resting solely on them with an (arguably) similar or greater load then your lumber racks. Sure it might work for a while but if you've seen trucks with years of overloaded lumber racks, the beds are no longer straight/strong. Keep it bearing on the bed floor only, or you're inducing unknown stresses into the truck bed sides.

Regarding the truck, 7200 gvw is a very light 3/4 ton gvw. Presume squarebody or GMT 400 or possibly pre "HD" GMT800 2500? But I think the non HD 2500s were 7700gvw at least.
GM 2500 trucks of that era went up to 8600gvw, with a few changes, but you're safe (presuming the truck is in good physical and mechanical condition) at 2000lbs of payload even with a very light duty Sierra 2500.

The only support the cabovers have on commercially built campers is along the side walls. It's not even 2x lumber. On a popup it's basically a 1x6. With a "north-south" bed, the overhang is around 6'.
Look at truss bridge design for inspiration. The trusses get built into your side walls and sheeted over. The road deck is your bed.

I actually tried to build an A-Liner Truck Cabin type camper to begin with but couldn't manage it. I also don't care for canvas sides because I boondock mostly. I actually own an A-liner pull behind now(needs rebuilt) and could probably build a TC that way now but it would likely be heavier from what I can see.

Several manufacturers are building their floor above the bed rails to give extra floor width so that's certainly doable. Campers are designed to be carried on the pickup bed, so if you're going to build one above the bed rails, you'll want to build it with a basement (great place for your tanks, batteries, and other heaving item storage). Remember, though the bed rails may be able to handle the weight you've put on them, if you build a camper that's 6' above that, you're raising the center of gravity and it will want to rock back and forth causing more stress on your bed rails.

***Link Removed*** makes campers that sit on the bed rails, but they are really just a shell that sits on top of the truck. They don't have sides or a floor below the bedrails. They're really nice and well constructed for what they are, but they're not a self contained camper.
As far as I know, none of the fully enclosed campers are designed to sit on the bed rails.

Your biggest issue is the truck. DIY probably means heavy and thatโs not where your truck shines. I think Iโd go with a popup style construction. That reduce the drag and weight.
