I did something similar, but I relocated the spare inside- no carrier. I just used a piece of black foam......about 1/4" thick to cover the 3 holes where the plate/ light was (but it's between the corner and the tub so you can still see the holes in the AEV corners). IDK....I think it looks fine.
I may have a better pic, but one kinda shows it-
