Seems like an idea to me - I see where you are coming from that there are people who wont get into the official clan run by PhatBambi who none-the-less still want to get some competitive games going.
Since he's been adopted as the THN BF2 community representative I think fi$hy should have a hand in helping to plan this through (if he's willing ?) I'm sure he can help you out getting some thoughts toegether LynxGB and it will mean that you aren't both working at cross purposes (i.e. where does the community begin and the second ED team end).
In short it sounds good and I hope that you get enough interest to make it viable. Since PhatBambi has run the main clan for a while now he might be a good person to have a word with in terms of advice on some sort of structure - i.e. who gets to determine the team and who resolves conflicts, updates notices, organises games, plans training ... There' s a whole raft of things to consider as you can see.
Taking all of the above asside for a moment there is one fundamental criteria before you do this. You have to be able to communicate and compromise - if you cant talk to people and resolve conflicts then this a non-starter. This is not a criticism but rather a fact of life when running a community - just ask all the people I've pissed off when I've done things badly and they will confirm
In short good luck - get planning and asking around for ideas. If you want any thoughts from me then come approach and I'll happily talk through ideas and thougts on how you might want to organise things. But first talk to fi$hy to avoid overlap! Bottom line, we'll happily put all the resources available to help you do this as long as you are prepared to put in the leg work to do it properly !
