I looked at that route too. I think you should be ok. The route is still going sideways, just in a different spot. The metal to cut out is really thin and easy to cut. You could just use a drill bit and drill a bunch of small holes in a 3" diameter and punch it out with a hammer. with a 2.75"-3" hole, you can use the original wiring grommet.
On a side note, if you go that route, try and find a 3" plug to fill the hole with. It allows a lot of motor noise into the cab if you don't.
