Will braces work on a thumbsucker, even if I wore a retainer for the rest of my life?

I've been sucking my thumb since a kid, I don't plan on or want to stop as it's a self soothing thing for me. I have a slight open bite and I am insecure about my teeth but I can't imagine stopping sucking my thumb. I have no problem wearing a retainer for the rest of my life. Would braces still be worth it in this case?
