All Special Modes

I think ALL of the special modes so far and in the future should be options in Custom Game, such as: URF, Doom Bots, Black Market Brawlers, etc. So even after the events/special modes are over friends who want to enjoy those fun modes still can. Rather than all of them being unplayable forever, also it would give respect to the coders, modelers, etc. who made those modes.

Another idea would be to have a graphics option for all the maps, such as being able to chose between Howling Abyss and Butchers Bridge for ARAM, and perhaps Season, Holiday, and Event theme layouts for Summoners Rift.
