Bunch'o'modes

Ok so a bunch of ideas for gamemodes:

Idea one: Who doesnt love a good survival vs waves? Been popular in many games and for many years, however this one is different. There are 5 champions and 1 spawn point for player champions and then a spawn point for the enemies, it is a map like the aram map. Basically what happens is that waves of minions come out (5 per champion, 3 melee 2 ranged) every 4 waves is a cannon minion that replaces a melee (so every minute, but this one also has a magic resist aura) also a super minion appears every 20 waves (every 5 minutes) and they try to make their way to the players nexus and destroy it, they attack anything that is generally in their line of sight as well. The minion waves come every 15 seconds and each wave they increase in hp by a direct % and their ad increases by a direct % as well. Now what makes this different than most others like this is that each champion can place 1 turret that is half as strong as the standard turret, so they can place them all together or they can spread them out evenly. The champions all spawn behind the nexus, they can only shop on death and they only gain gold over time unless a gold income item is bought, also the spawning pool does not heal, the nexus does but that effect is blocked if any minions are within an area of the nexus. aaand to make it harder AoE abilities are weaker in this game mode.

Idea 2: A custom game setting for summoners rift, where you can have 6 players on each team, but the sixth player doesnt have a champion, they control the npc's, by this i mean they can tell the minions who to attack in their lane and what the turrets fire at. (the person can not make the turrets aim a champion if 2 or more minions are in its range) and the minions cannot move away from their lane but can attack anyone within the lane (minions still run along the set path but can only stray a certain distance away from the line)

Third idea: is where champions start at level 18 and slowly decline down to level 6 losing abilities randomly but keeping level 1 of each when they reach level 6, once they reach level 6 they have 2 skill points (because 1 in each skill would be 4/6) to put onto whichever of the 3 main abilities they choose.

Also a possible little side thing could be champions can go to level 20 and they can put 2 skill points into their passive making them slightly better for example viegar gets an extra 2% per 1% of mana missing when it gets leveled up instead of 1% or another example lissandra 18 seconds for a free ability goes down to 15, then 12
