Sure but having a Mexican El Escorpión character in FO4 would pique my interest so I might play it again. He could be a Mexican restaurant worker who managed to get into the Telemundo vault and found the costume in the TV studio when it opened. Or if he/she isn't Mexican but Puerto Rican and did/said what he believes a Mexican would do (like confusing Dia de los Muertos with Cinco de Mayo).
All the Bethesda iterations of Fallout lack the occasional wackiness of the Black Isle/Obsidian games, like the occasional Alien reference or the Kings faction. That light silliness isn't present in anything Bethesda has put out (the Mothership Zeta DLC is a good example, Bethesda bashes you over the head with the little green men).
