For those who want Odyssey Augs in regular games
The short answer is, it probably isn't going to happen.
HOWEVER, .. There is a president for something like this that already exists within the game, and I could see Riot taking this concept further for a future champion.
Gangplank
Death's Daughter 
: An initial cannonball lands in the center of the barrage, dealing a cluster's worth of true damage to all enemies it hits and slowing them by 60% for 1.5 seconds.
Raise Morale 
: The barrage grants allies 30% bonus movement speed while they are inside the area, persisting for 2 seconds after leaving it.
Fire At Will 
: Cannon Barrage fires「 6 additional waves 」 over its duration.
These are basically augments for his ultimate.
I could see Riot release a champion who has significantly more option to use gold or some currency that is exclusive to them, like how Gangplank gains Silver Serpents, in order to purchase augments that change the way their abilities function in a similar way to how the Odyssey Augments work.
