Nah, when they reach Raftel, the Mugiwara will have a giant sign pop out of nowhere saying, "You won!" Then a midget will run up and kick Luffy in the nuts.
Being serious, here's the ministories I'd like to see:
Don Gin's Pirate Armada: The story of Gin and his trials through the Grand Line.
Kuro and the Davy Back Games: Kuro's unmatched speed vs. Foxy's Noro Noro Beam. Plus, the KuroNeko Flag looks similar to Foxy's.
Gamon's Seaking adventure: Gamon's island threatens to get flooded, so he and the animals build an ark. The ark gets eaten by a Seaking, but Gamon saves the day.
Blackbeard in Skypiea: Blackbeard ends up in Skypiea after getting hit by a second Knockup Stream, and reach land just after the Mugiwara leave. They find Cyandora and try to steal the gold, only to get beat up by Gan Forr and ejected from Skypiea via an Impact dial attached to a giant slingshot.
Adventures of Eyelashes and friends: Eyelashes, Scissors and Carue get lost in Alabasta and fall into a sinkhole. There, they find a broken piece of Pluton.
Makino the Pirate: Makino reads the paper and sees Luffy's new bounty, and tries (Unsucessfully) to make a pirate crew to follow him to the Grand Line.
Pearl's Jewelry business: Pearl leaves Don Gin's crew and ends up in Loguetown. He makes a fortune off pearl-diving and starts a jewelry business.
