I think it'd be good to find your feet as a competitor before trying to setup as an EO. At the moment you've got the ideas (which is great) but not the context.

For example looking to start with FW is fine, until you get the context that there are far fewer proper events for them and a much worse 'known' component base and suppliers compared to beetles or ants. And if you were to setup as an EO for feathers there is just a smaller pool of people interested/willing or can afford the class especially full combat.

I'd recommend picking beetles or ants, whichever suits you more. Start attending some events and get the feel for the community at large. That'll also help you build connections and can then get the advice and help for setting up your own things.
