1kg of ABS should be around 70-100$. Depending if you have the printer handy, it's doable to print a backplate.
It is however most likely not going to be functional. Typical methods of printing use a filament that they will place on the printing bed and build the object layer after layer. This makes them very brittle. Now you could use other methods, eg SLS (or SLA), but then your price shoots through the roof.
I'll just clarify my response about "sidemount", because some didn't understand it. Many sidemount rigs have no inherent weight (no metal plates), and if you scrap the d-rings as well, there's just bare webbing left.

Hmm... if similar in weight to aluminum, what's the advantage?

I second Akimbo :
Aqua Tank Back Pack with Straps
There's no need to spend a ton of money here - all you need to do is secure the tank to the pack and secure the pack to your body. It's not rocket science

I was inspired by this project using the Oxy ultralight and the DSS Tropical wing. In fact here's the video that Ronscuba posted many years back:
...so I went out and purchased the Mares XR to use with my DSS Torus 26. The tank bands fit through the openings pretty well (a little tight), but none of the grommets line up at all.
Since it's the tank bands that really hold the wing in place anyway (on a DSS wing, no STA), not the thumbscrews or rubber fasteners, would anyone see any problem with not having the wing actually attached to the backplate? It's not like the rubber fasteners were ever load-bearing in the first place.
It's not a problem. Just annoying when you're changing tanks.

Yeah, that was the only drawback I could see.
Looks like you could fix it with a drill or maybe a hot soldering iron...

Might be a stupid question but how is possible you be overweighted with just a aluminum backplate? Is that normal without a wetsuit? ( I never dived in warm water like that 
)

It's highly unlikely: with a very heavy tank, no body fat, and a few steel joints I guess it might be doable in fresh water. Al plate and the webbing are normally about neutral, so all the weight is in the tank. Plus the body composition -- like Wolverine with densonium bone grafts or something.
