Is this a good domain name?

I made a website to promote my short films, animations, and games and the collective name for all these forms of entertainment is The Underground-Studio. However, 99% of the time, the site and content will be referred to as u-stu. Do you think once a fanbase is established, that u-stu.com will be a good domain name? I know that now it doesn't make sense but once my audiences online community knows of U-Stu (Yoo Stoo / Yoo hyphen Stoo) it will be good. I'm mostly concerned with how you feel about the hyphen.
