kxms.webmaster

Hello, Could the domain name for my account be changed to kxms.heliohost.org from kxms.net? I originally meant to use kxms.heliohost.org as my user name, but I believe that I have registered incorrectly. kxms.net is too close to another domain name that I fear my website may compete with, and I do not want to risk a trademark violation. Thank you very much for your help in this matter.
