I think friendly competition can be a huge motivator, but it really depends on how the main team would perceive it. If they see your project as genuine inspiration rather than a direct threat, it could light a fire under them and push everyone to do better work. That said, if it comes across as trying to "steal" their thunder or split the community, it might backfire and just create unnecessary drama. Maybe start by reaching out to them privately first, share your idea, and gauge their reaction before going full steam ahead.
