2016 SE TSI - toggle switch for blank buttons?

Hey all,

I have a 2016 SE TSI with connectivity, and next to the push to start button I have 4 blank panels. I know i'm getting the ABS disable button, but i'm also trying to install a covered (think missile launch switch) switch to toggle emergency lights (i'm a first responder). While I could do it the "field expedient" way with a toggle switch next to the headlights on the easily replacable trim bit, I was trying to make it look a little bit smoother.

I'm eyeing a switch like this: https://www.amazon.com/Support-Cover-Rocker-Toggle-Switch/dp/B0154JY8OA/

however that switch has too big of a body to fit in the space provided.

Any suggestions? Thanks!
