The technical answer: anybody can start a project.
The more practical answer: considering there are 9586730495876 projects currently in production already, and considering you have a grand total of 4 posts, odds are low you'll be able to successfully get a project going at this point. The better known you are in the community, the more likely people are to join your project (yes, I know the grammar of that sentance was fucked up. stfu).
However, I made a similar prediction about the Xenogears project, and that seems to be comming along pretty well, so I could be wrong.
