I am joining this contest hugely late with a "what if" scene where the movies Mad Max: Beyond Thunderdome and Mad Max: Fury Road meet the universe of Fallout.
It shows the hypothetic situation in which a legion of War Boys (from MM: Fury Road) survived the death of Immortan Joe and conquered Bartertown (from MM: Beyond Thunderdome).
Somehow, in its market they found strange weapons traded from a land far away and their strongest warriors took them to fight in the Thunderdome. The winner would be their new warlord.
This is the arena from the old movie:
