Ideas for next Skyrim DLC?

(Please read all) I know Dragonborn wasn't long ago and that Bethesda are taking their time with the PS3 (I disagree with them doing that). However, I believe that we should have an arena based DLC next. One with multiple ways to get started in. For example, an arena being built in Skyrim as friendly competition for those that volunteer and those from The Imperial Arena. You can start out as being captured by Imperials and forced to fight in your execution and by winning (with new execution kills) you are sent to underground fighting areas to gain small amounts of fame before you join the arena and win your freedom in multiple grudge matches of different kinds, involving new unique weaponry and armour (start off in standard garbs, then proper gladiator themed armour and eventually choose your own themed armou), new fighting styles which can be changed through interactions with a trainer (faster swinging yet smaller damage and different swings/power attacks or slower yet more powerful swings and so on). A new storyline can be built from this as you earn a name for yourself and make friends/enemies based on choices and when freedom is earned you are rewarded and allowed to come back and practice. You take part in training with wooden swords that can only beat people into submission and new active effects can be earned. Or you can join altogether willingly by executing a dangerous prisoner as part of a qualifying match and then must earn a big enough reputation before an invite is issued. Underground fights means wearing a collar so as no magic can be used and only personal combat. Unarmed skill tree and new unarmed moves as well to be given. More challenges to duels outside as renown is gained.

This is my idea for a new DLC, what do you guys think and is their any you'd like to add??

If you like this idea then please share it around other forums in the hopes that it is made, a longer DLC than Dawnguard but with few new areas and content but great replay
