Today's Plotbunny flavor is: Star Wars Crack.

Neither of these seem terribly original to me, but the ideas amused me nonetheless:

1. Obi-Wan Kenobi and Darth Maul are recruited by the White Guardian to fetch the 18 pieces of the Key to Space.  (If he's got one for time, it just figures he'd have one for space, y'know?)  
2. Jar Jar Binks is the Chosen One of the Jedi and falls to the Dark Side.  Provisional title: "Qui-Gon got it a bit wrong." 

(Actually, I'm half-tempted to make this fanon: Jar Jar Binks has Super Duper Force Potential.  (Click the link and read how this is not such a crazy idea.  Go on, you know you want to.)  He can't control it, and causes accidents that get him banished from Gungan society.  He runs into Qui-Gon and Obi-Wan, owes Qui-Gon a life debt, goes along on their adventure.  For the purposes of this nutty theory, Qui-Gon has a weakness in that he's not all that great at sensing untapped Force potential.  When they land on Tatooine and run into Anakin who also has Force potential, the combined aura of Jar Jar and Anakin is enough to trigger Qui-Gon's spidey sense, so he mistakenly assumes that Anakin must have Super-Duper Force Potential. 
( Cut for midichlorian fanon and a total reinterpretation of the Star Wars Saga as a giant case of Mistaken Identity. )
