Rear Bucket seat 2022 GMC option?

[sasq40]

I'm wanting to convert one of my field trucks into a 3 seater, Currently i remove all the back seat components and place plywood on the bottom and back for the techs to keep equipment in tools. I need to make a training truck that will house 3 guys in. Id like to throw just the 40 piece in there but don't like having the full backrest these new models have. Is there anyone who's done such a thing. Im currently thinking about just cutting the rear back of the seat but wondering if there are other options

It'd be nice if the 2nd row captain chairs from the SUV's would bolt in... as you're aware though, the rear wall would be unfinished too, nor would there be room for them to recline either.
