Is there any way to exploit the console by a glitch like this one, a bit similar to the savegame transfered to a Wii when we were loading character customization of Lego Indiana Jones back on the Wii ?
Game exploits are unlikely to be a thing on switch. According to SciresM, you need two usable vulnerabilities for the game: a info leak and a buffer overflow. You need the info leak to get around the ASLR, and then the buffer overflow to start ROP. It's very unlikely you'll have a game with both of those.
