More customization in custom games

I just had a thought that I wanted to relay on the forums. Whenever I play a custom game, I feel as if the term "custom" sort of loses its meaning in that case. What I'm proposing is the following: 1.) The ability to change the number of items slots (increase, decrease, etc.) 2.) The ability to determine turret armor & health 3.) Altering the number of objectives on the map (i.e. adding a second drag, getting rid of blue buff, adding turrets) 4.) A system where the creator of a match can invite another person mid-game, and have them join, automatically leveling up to the person with the lowest level in-game, without having to re-create the lobby 5.) Access to all champions and skins (so that people can test out champions and see how certain skins look without having to wait for the rotation) 6.) Being able to switch teams mid-game (which could be helpful in the event that there is a 3v2 and a player on the latter team leaves) 7.) Giving people buffs (increased/decreased mana regen, health regen, AD, AP, etc.)

These are just a few of the things that I personally feel would make custom games more fun to play. Of course, the game creator should be able to customize all of these features in a Settings menu in the pre-game lobby. Other than that, I think these additions would greatly heighten the appeal of custom games. :)
