Wrote this on someone's post but decided it deserves its own.
Disclaimer: I'm up late and am tired of writing but decided this was pretty funny and cool after seeing someone's idea for a new champion. This is purely a joke and for laughs.
What if we had a Champion of Minions? This Champion or rather this minion grew tired of all the minions who were turned and forced to fight their brothers/sisters in arm against one another. Each being slain numerous times throughout League's existence... This minion (Champion) decided to take matters into their own hands (idk what minions has for hands) and started to work out, cast magic, learn to fight, etc. It became a strong minion (winion) and then eventually outdid itself and became Champion of all Minions.
This Champion of all Minions decided to enter unannounced to League's biggest battle of the year (MSI or something idk i dont keep up with LCS no more) and entered the battle field for the first time. Knocking down some powerful champions. Eventually falling down to a gank of several confussled champions. When suddenly this Champion of all Minions respawns. WHAAAAAAAAAAAAAAT?! The Creators or whoever is in charge of the Summoners Rift decided this Champion of all Minions was worthy of a spot in the League of Legends. Dun dun dunnnnnn
Champion of all Minions Passive: Battle Cry For each minion ally who has fallen victim to League, Champion of all Minions gain .0X stats (AD or AP or Armor or Magic Resist or whatever stat) per Minion. Q: Minion strike, that deals percentage health (just a normal minion strike) W: Minion Dash, walks a certain direction. E: Minion Stun, stuns a target(s) X duration. R: Minion Wave, summons a wave of minion (level 1 would be normal wave, level 2 would be a wave with the cannon minion in banner of command or maybe this minion just looks super angry and lastly level 3 ultimate would be winions)
Sorry I was just bored... but your idea sounds pretty nice except there are way too many champions that has parts of them inside this new concept. Maybe have a few and then share a backstory of why they resemble one another but the new concept is unique because it's different in this aspect. Nonetheless, nice.
Edit: I didn't want to detail the abilities as I am late up at night.
Edit 2: Also why hasn't Riot released any Emotes with Minions!? #MINIONSLIVESMATTERS!
