It looks like you’re using a standard nylon or vinyl insulated ring terminal, but those are often rated to no more than 100c. Wouldn’t it be necessary to use a high temp ring terminal if it’s going to make contact with the bed?
I don’t think it’s a matter of whether or not you can. These types of mods have to be DIY’d to any printer. I haven’t done one myself yet (looking into it and still concerned about the PSU requirements), but in your case it’s probably a matter of whether or not the 300x300 bed fits your printer and if you can (and are comfortable) with wiring it. This guy did a mains wired silicone bed to a CR10S if that helps. Looks a bit more complicated, since the CR10S has adapter style plugs that need to be unsoldered. https://www.youtube.com/watch?v=IhjqfMHy...
