What should I do?

So I am adding 2 receptacles to my room, the receptacle I’m getting power from had a metal box and is pic 1, but as you can see the cavity is only 2 1/2 inches, I’m putting the metal box back in but as you see in pic 2 being that the cavity is only 2 1/2 the old work recep box (14.0cu) is like 2 3/4 and sticks out a little. Pic 3 is so you can see how it looks with the recep and cover, I would leave it like that but I know my wife….lol….Do they sell a slimmer box? Or do they sell a recep cover that can cover the gap?
