If you are going succeed in this venture, that is to have a team etc, I believe you should have your dedicated website and also have a forum there, something like the Ubuntu-Budgie forum. You’d also have to compete with Linux Mint for users. There’s also Feren OS, based on Linux Mint out there, which once was supposed to be fully rolling and cutting edge, but not any more.
The thing is, the interest in Linux distros appears to be waning, not many forums have a significant community around nowadays. There had been a vibrant group of people once, testing every new Ubuntu release, but that too is practically gone. So, this would be an uphill task. Hope you’d succeed anyway. If you would be able to gather enough people around you, you’d succeed, but you should have your own web site.
