Yes, it's been done. I added one this summer. I used a regular 120V light switch and mounted it to the frame at the side of the compartment door. The wires to the overhead light were just hanging there, so rerouting one of them was simple to install the switch in the circuit. Then just leave the overhead fixture switch in the on position.
I've picked up a 12V lighted indicator switch to replace the 120V one, but need to modify a box cover to fit it.
