Hi, I only have a pal snes console. Is it allowed to mod it and use a 50/60hz switch to play the japanese version with an everdrive to submit a run?

Greetings to everyone, I'm new to this forum and I try to run Super Ghouls n Ghosts. I was running the game ~6years ago on the europe version. At the moment I try to get back into it and after some practice to change to the much harder, but faster Japanese version. I already submitted a run, not very good but it fits in the list - I just need an incentive :-)
