Hot tip for anyone playing a commercially written roleplaying adventure: If you find a room with a rack of uniforms, be they military, security, or demon-cult acolyte robes, you're meant to try putting them on as a disguise before you infiltrate the enemy base further.
Which means you should probably avoid them at all costs.
[Reminder: Our guest commentators have not seen Rogue One. Part of the fun is seeing how their untainted impressions re-interpret the movie through the lens of our comic.]
I feel like if K-2 could, he'd sneak off and get a built-in-weapons upgrade so he'll always have a gun Cassian can't take away.
That being said, we don't actually know that he hasn't done such a thing. It does seem practical, and Cassian would have no reason to know about it.
I guess we'll find out sooner or later.

I think the evil overlord list had something to say about helmets, and being able to see the people inside the helmet. You know, to stop an intruder from simply putting on your uniform, and then since you can't see the person's face you have no idea who they are.
But the whole "put on the uniform and blend in" concept is such a staple of fiction.
Meanwhile, Sally/K has the appropriate line of thought. Shoot first, blend in later. I like how she considers behaving as "I won't shoot anyone as long as I don't have a gun".

[SFX]: draaag.... {the crew drag an unconscious clone trooper inside the shuttle}
Cassian: Now we've got the blasting out of the way...
Bria: Ooh! They have Imperial uniforms.
Cassian: Now you're thinking what I'm thinking.
Bria: Yeah! That +1 Armour bonus is a strict upgrade!
Cassian: Sooo... let's put on the Imperial uniforms and walk casually towards the data facility, and see if they notice anything out of the ordinary.
K-2SO: They'll notice something out of the ordinary when we shoot them!
Cassian: K. Your gun, please.
K-2SO: Awww.
Cassian: You can have this back if you behave.
K-2SO: Okay. I won't shoot anyone as long as I don't have a gun.
