Question about Cab Lights

First off, Ill start by saying I love a lot of lights. With that being said, I was wanting to add 5 more cab lights. I was going to get the current 5 taken off, do the body work to refill the holes up there, and then redrill for 10 lights. My question is this, is there any certain curves to the factory cab lights, that wouldnt allow for this? I was looking into a set of LED cab lights on ebay, but I didnt want to get these lights if there is going to be an issue with the curve in the roof.

Any input is appreciated,
Thanks,
Justin
