@Riot So about this Rotating Game Mode Queue

I was just reading about the Rotating Game mode Queue and while I think it sounds like a really cool idea, I have a few questions on how it's going to work. Here I go:

1. Will each game mode have it's own list of banned champs?

   For those who don't know what I'm talking about, during URF, there was a small list of champs that couldn't be played during the game, and in One for All, both Karthus and Teemo were banned during the event due to "potential Toxic playstyles", my question is, will each game mode have particular champs that couldn't be played, or will certain champs be tweaked specifically during these games so they too can be played?

2. Will there be new items specific to certain game modes?

     From what I remember, Black Market Brawlers had it's own slew of special bilgewater items that accompanied the game mode that it used (I don't know much about it, I never actually played it). My question is that for each game mode, will there be any new items to go with those particular game modes? On the flipside, will there be certain items omitted from these game modes?
   

3. Will we see the return of Butcher's Bridge, or even new maps?

     While I never played BMB, I did play ARAM on the Butcher's Bridge and I rather liked the idea of different variations on maps, so I'm curious if we'll see it's triumphant return. On top of that, I'm also interested if we'll ever see a new map to fit some game modes, like an official shuriman map if Ascended comes back, or perhaps even a Piltover/Zaun map on URF or something like that. 
   

4. Future Featured Features? (Try saying this 5 times fast LOL)

     Once this goes live, will all future featured game modes be permanently put into this cycle? I mean depending on how successful the featured game mode is, will it permanently make it into the featured Queue automatically? or will we have to wait about a month maybe to gather data first?
   

Just a few questions and thoughts I had about this new Featured Game Queue, What are your thought? Riot Feedback is appreciated! :D
