How to tie the lore into the game and an explanation for nexus's

With my idea the game and lore will be almost completely separated. The only time they collide is with artifacts and relics from the lore. Ok so with my idea summoners still call upon champions to fight for them in order to settle debuts and other conflicts. However summoners now place artifacts, and relics of champions and monsters of the past or present into a nexus. Once the relic is placed in the nexus a "ghost/ avatar"of said champion is summoned to the rift. For example if a player chooses gangplank, inside the nexus you would see one of his pistols for someone like Cho 'Gath maybe a tooth. Regardless once the champions are summoned they fight desperately to destroy the enemies nexus in order to prevent the nexus from calling upon another ghost/avatar. Once the enemy nexus is destroyed the other team wins because there is no one left to fight against. I think if this was done it would allow the lore team to write without restriction and allows us the players to feel as if we are still calling upon our favorite champs.
