Yeah... super weird.
I actually did miss earlier where you spoke about transparency and how the committee would be put together. That sort of thing is important, and while I don't agree with not having defined limits on how long you can be on the committee, any answer at all is better than not having an idea.
Honestly though, when you look at this objectively, a group like this would be nothing more than a committee that oversees and play-tests bans and then sends that playtest data up the ladder? Why not just write out actual criteria that awards a pokemon a ban? If you do that then people can go and look up the playtests for the pokemon and see where they exceed that criteria to know why it's banned. You wouldn't even really need to take votes. You'd just need volunteers with some PvP skill to run the playtests.
I mean, unless you had dreams of tiering out PvP a la smogon. Which a lot of people would have mixed feelings about. (Staff probably wouldn't go for that since it'd mean changes to the PvP UI, and this whole council thing has been tried before, so you're fighting an uphill battle already.). If you did, it would be meta-healthy in that less mechanically efficient pokemon would see play, but there'd be some immersion loss. I'd recommend against trying to make an official list of OU-type, but not banned pokemon. There's really no reason to write players a connect the dots to the most meta-efficient teams.
Another big difference with PRO is the seasonal competition. The committee would have to always be performing their tests in anticipation of the next season, since 1 month isn't a very long time and you'll want to have more complete test data kicking off the season, rather than having to try and push emergency patches mid-season which is where you'll get more flak from your player base.
I was never a "-1" vote on this (calling it a council is super cheesy though), but if you're going to do it, you have to come loaded with an idea of how you're going to do the job and do it fairly or staff isn't even going to give this a second thought.
