If they're going to keep going with 1980's sequels, they're probably going to go ahead with another one they'd been discussing.
Last Starfighter 2.
And no, I'm not kidding. The pitched premise didn't actually sound bad, either, if they didn't screw it up. Same actor, but...more about his son as well, and needing to get more starfighters from Earth, because we're apparently good at that sort of thing. Lots of gamers.
That could actually be fun. If they gave it to the same writers as Galaxy Quest, it could be hilarious. And yes, I'd not mind seeing an all-out battle with Gunstars done by ILM. I always liked the design of those. So did J. Michael Strazinsky, because he stole it.
I mean...just picture a fish-out-of-water thing, like Galaxy Quest, but with typical hardcore Halo/Battlefield/etc...gamers thrown into real strategy planning and real starfighters. That could be fun.
