110 wiring help

Are there any issues with replacing a 3 way switch setup with 15A outlets to use for L1 charging? In my garage I have an existing 3 way switches to control the interior light from the front overhead door and a rear access door. I would like to leave this always hot as the garage door is plugged into the light socket extension. I also would like to add a GFCI to the circuit as added protection. Thanks for the technical help.

For what it's worth, my garage has a GFCI outlet (and the EVSE has one also) yet when I accidentally overloaded the circuit by running a shop vac while my car was plugged in, it tripped the breaker not the ground fault protection.
In my book, overloading a circuit by drawing more amperes than what a circuit is designed to carry shouldn't cause a Ground Fault Circuit Interrupter to trip. A GFCI monitors for unwanted current flow between either conductor and ground, indicating an unintended current flow such as through your body or water, and trips in milliseconds. Your circuit breaker, though, is designed to trip when overloaded for a few seconds, to protect the wiring from overheating.
