IMO, this is not the way to go. RD threads were tried before and I did not think they were particularly effective. What needs to be done is to split OT on content, not requested moderation status. I'm also fine with just merging it back to the way things were.
Splitting OT on content rather than moderation was my first thought as well, except the content sections in the Colosseum are all mostly dead. You can see by amount of people browsing at any one time and when sorted by last post.
There are folks who want to re-unite the OT cause they're saying it was better before the Tavern/Chamber split, and then you've got

who say it was better before with even less sections. The mods are saying there needs be some area that they can moderate so it can't be all Tavern rules; must have either a Chamber or Red Diamonds. When I stop and think about advantage/disadvantage between a 'moderation by forum' Chamber system and a 'moderation by thread' RD system it's not even close.
If it comes down to
which subforum a thread is located in and
what is the best layout for those subforums, a simple solution could be to have only:
..and fold everything from WH, A&E, Sports, etc into one of those three sections. So you'd start in the middle in Tavern and have easy access to the other two. For all the threads in the forums that got closed you could set a date where everything goes into the Tavern unless the original poster requests one of the other two.
Chamber standards could be less about "mature" discussion and more about effort. Things like having content in the original post, replies that stick to the topic of the thread and strict adherence to the Civility rules. Basement could be the opposite and the place to put things like serial picture threads, maybe with no postcount. Tavern becomes somewhere in the middle of that. I dunno maybe some sections have enough activity that they're worth saving so they could become a subforum of whichever rules standard they belong under.
A tutorial for the OT section that tells how to set your subscriptions with My Account, effective searching for threads and the use of Tags might be useful for this system. Maybe there is a way edit tags into preexisting threads too.
If you don't want to get rid of it, just hide
DanQ's Personal OT Forum somewhere else, like under News Updates. : P
