4 speed floor pan to automatic

wouldnt the floor pan look goofy with the 4 speed hump and no 4-speed shifter? he has a brand new carpet kit for the 4-speed hump. wonder if i could just put a cover over the shifter hole and bolt my b&m shifter to the hump?
I bought a car that had a patch over the shifter hole in the hump and it had an aftermarker auto shifter. It looked ok to me plus was a nice flat area to mount the shifter.
