Dedicated Server for Xbox

Could we just buy a remote server, setup a minecraft server on it using a secondary xbox live profile with gold using the phantom project, then whitelist people to the server by adding them as friends and add parental controls to stop unwanted people adding you this having a cross platform remotely hosted dedicated server? Mojang you just have a more efficient version of this given the server tech they recently acquired and the relationship they have with microsoft. Maybe get some ghost profiles so it is setup to do this?
