I don't know that the design team put as much thought into these fictional weapons as one might think. They designed something that looked absolutely badass that would play well on-screen...and that was it.
Movie aesthetics was a defining element, sure, but with a lot of real world factors considered.
The whole thing of using Vietnam-esque kit to convey certain messages about the world and the culture, for example. Making futuristic weaponry that still resembled real world weapons of the day, instead of outright space lasers. I always thought the Smartguns were the most impractical pieces of junk ever, until I had a go with a couple of real weight ones at a drop and suddenly they made a world of sense... Arms companies are even trying out versions of the same concept today.
You also have limitations of film, too.
For example, I don't think we ever
see anyone use the Thompson mag release lever, so the tabs could very easily work. Same for 99 rounds of 10mm caseless when all we actually see is a blurred .45 stick mag, or battery powered shoulder lamps even though we might see the mains cable trailing in the edge of shot...
In light of this, we could probably assume certain things, like the stocks being made of a material that won't bend as easily as they might appear, for example.

Make no mistake, these in-universe guns were designed with the 80s version of 'tacticool'. Sleek, flashy and badass. When it comes to the topic of improving them, I believe applying real world sensibilities is not asking too much.
Not too much, no, but remember that these things looked like viable kit because they were built on stuff from two decades earlier, or in the case of weapons as early as WW2... It looked cool because it was all futuristic, but it looked plausible by looking like hardy old military tech.
The problem with current day Tacticool is that there's *so* much choice and customisation for everything - In a military environment, especially back then and in the Aliens world, you generally get what you're given... and that tends to be cheap, hard-wearing junk made by the lowest bidder. If your kit is so cool that you can't complain about it, it's not military!

The PR is indeed bulky, but it's also pretty free of snag points thanks to the shroud and various guards. Very few current weapons are that snag-free, a lot of which is down to the various add-ons.

Things integrated into a redesigned shroud is what I would expect (and would love to see on a new build).
This is the way to go, I reckon - Rear iron sight inside the existing sight channel, incorporating a flip-up reflector for reflex shooting and possibly other display modes, like Infrared. Adding a digital sensor array to the front edge of the shoud (possibly recessed for protection) can allow for magnifiied views and rangefinder overlay in the same reflector, as well as laser target designation if needs be.
