And speaking of the custom name list, since the OP didn't have one prepared, I took it upon myself. I've prepared a civilian version (use this if you want "Ava" to become "Hana Song" and "Sonya" to become "Lena Oxton", for example) and an OW aliases version (for if you want "Ava" to become "D.Va", "Sonya" to become "Tracer", and so on). To use, open the file you prefer in notepad, select all, copy, and then in the game, go to the settings page (tip: right-click twice will open the phone even if the button for it isn't onscreen at the moment) and click "Import Names".
