Can I replace stock fog lights with 2x2 LED squares?

So I really think it would look sweet if I replaced the stock circle fog lights with two 2x2 LED cube lights. Can someone maybe point me in the right direction on how to do this?

Change these:


To these (or something similar):

 

remove round light... mark a square, cut a square, and then just look for a sturdy place to attach. drill a hole and bolt 'er up.

while i dont have a factory bumper, i replaced the fog lights with Rigid duallys with the diffused lense, great for a fog light and a wide spread, but i would look into a flood pattern if i did it again. (incase you had to choose)
