You don’t need to Isekai yourself into FFXIV to bring about potentially calamitous engineering incidents; just get into hardware design and find new and exciting ways to let the magic smoke out of things!

Joking aside, nah… if I had to end up in the world of this game myself, I would be perfectly content to be my character as she stands.
