If you had to change your name, what would your new name be?

Is this a witness protection inquiry? I can think of a reason I would want to change my name l, I have had it for 57 years and I am pretty comfortable with it. Could I change my name to Elon Musk, or Jeff Bezos for 24 to 48 hours and have access to their  obscene wealth in order to siphon off a couple million that they would never miss? Maybe that would be a temporary option . 🤣🤣
