I think you're overcomplicating this. Flare the existing metal lines and run fresh metal lines or AN call it a day.

I wouldn't remove a cooler, nice to have such a thing.
That’s where I’m at. Plus it give me an excuse to buy pretty stainless hoses

As for your flexplate cover,a 4x4 cover is cast and has bosses for braces to attach to. Your missing the braces also. At this point a 2wd cover is better than nothing,until you find braces and a 4wd cover. I actually ran with no cover in the past,I ran over a basketball I didn't see and wound it up in the flex plate,yes,something is better than nothing

I am in the camp that the oil cooler is overkill unless you plan on doing heavy hauling. I did an LS swap on my blazer and deleted the oil cooler. I feel my application is a lot lighter than what that application was originally designed for. If you plan on keeping the cooler, I would change the fittings to AN and make AN lines to the cooler.

Lots of info out there on those old big blocks with those fittings.
Small plugs (like freeze plugs) or tapping them for threaded fittings was usual way back in the day.

Dead link here's a pic I stole from @SquareRoot
Thank you

Yes that’s it. What are the braces bracing? Like keeping the cover in place? Or supporting the weight of the tranny?

Looks like they bolt to the frame or crossmember? I would think the 6 bolts would hold the cover on?
