I don't see why it would be a problem. People use different names on credit cards all the time. They get married, or divorced (after taking their spouse's name), without changing names on their credit cards, use their middle name as their first name, use nicknames, etc. I doubt banks care as long as you use your legitimate SSN and pay your bills. On financial accounts where you have assets, I wouldn't want to use an unofficial name. If there's a dispute they could claim that you're not the owner, and you risk losing the assets.
