What if William Hanna and Joseph Barbera worked for Warner Bros. after leaving MGM and retained the rights for Tom and Jerry?/Bugs Bunny's Treasure Hunt

Bugs Bunny's Treasure Hunt is an animated television series produced by Hanna-Barbera and Warner Bros. Animation featuring the Looney Tunes/Merrie Melodies cast. It premiered in syndication in late 1985 and would be the last cartoon to star Daws Butler as the voice of Yogi Bear and the penultimate to star Mel Blanc as the voice of Bugs Bunny.

Plot
Bugs Bunny and his friends would go on treasure hunts around the world, as assigned by Granny. They traveled aboard their ship, the S.S. Jelly Roger, which strongly resembled (but was slightly different from) the ark from Bugs' Gang. Elmer Fudd, Yosemite Sam, Dick Dastardly and his three henchmen traveled on their ship, the S.S. Dirty Tricks, and would try to beat Bugs and friends to the treasure by engaging in their usual dirty tricks.
