Actually the DS Gunner's basic black jumpsuit was a uniform DS Troopers were wearing in ROTJ pretty frequently (on Endor and on the Death Star, though there were also tuniced ones on the Deaht Star).
So I'd NOT mind that, but I'd still prefer a new SA Tuniced Death Star Trooper, no doubt...

And it'd definitely not be accurate for the DST's in A New HOpe... Though I think that one at the gunner station for the super laser maybe was wearing a jumpsuit, I forget now. The majority were definitely the guys in tunics, and there's definitely a grey tuniced "Officer" DST in one of the command consoles in scenes with Tarkin. In particular I believe the scene where he has Leia brought to him to blow up Alderaan.
I saw a cool bit of cut footage once of that scene without the special effects and not edited together. You can see the DS Trooper in that console clear as sunshine and he's in a grey officer's uniform but wearing the black helmet and gauntlets. Very cool...

I'd love that vintage Death Squad Commander paint variant then.
Anyway, I'm obviously drifting here.
