Can I fake being a "real" mute?

Can I fake being a "real" mute? It's been getting worse lately, and I don't think I could successfully say anything to anyone anymore, no matter how much time I'm given. If I moved somewhere where no one knows me, could I fake being a "real" mute? Would that be morally wrong? Would it be more difficult than just not talking to anyone? If it's possible, what do I have to learn/do?
