What if William Hanna and Joseph Barbera worked for Warner Bros. after leaving MGM and retained the rights for Tom and Jerry

What if William Hanna and Joseph Barbera worked for Warner Bros. after leaving MGM and retained the rights for Tom and Jerry? Well, here's what might happen.

History
Following the Metro-Goldwyn-Mayer cartoon studio closedown in early 1957, William Hanna and Joseph Barbera, contemplating their future while completing the final Tom and Jerry cartoons, began producing animated TV commercials. During their final year at MGM, they developed a concept for an animated TV program about a dog and cat in various misadventures. After they failed to convince the studio to back their venture, Hanna and Barbera were convinced by fellow animators Friz Freleng and Robert McKimson to join the Warner Bros. Cartoons unit. As a result, both producers signed a deal with Warner Bros. to finance their projects and as part of the deal, the production rights for Tom and Jerry (created by the duo) and Droopy (created by former Warner Bros. animator Tex Avery) were acquired by the studio, forming the newly-founded Hanna-Barbera Productions as a separate unit of Warner Bros. Pictures. The Tom and Jerry and Droopy series were integrated in the Looney Tunes/Merrie Melodies franchise (with their MGM shorts being reissued as Looney Tunes/Merrie Melodies shorts), while Spike and Tyke star in their own shorts (with their cartoons (except the ones where Spike appears whitout Tyke) with Tom and Jerry beign reissued as Spike and Tyke cartoons), while Tom and Jerry also star in cartoons without each other (with Tom being an antagonist for some other characters at most of his solo cartoons), resulting on Hanna and Barbera starting to work on the series, with new characters like Huckleberry Hound, Pixie and Dixie, Yogi Bear, etc. being part of the Looney Tunes/Merrie Melodies cast (as well as television-exclusive Looney Tunes/Merrie Melodies characters for The Bugs Bunny Show such as Magilla Gorilla, Peter Potamus and So-So, Atom Ant, the Hillbilly Bears, Secret Squirrel, Squiddly Diddly, Dick Dastardly and the Vulture Squadron (Muttley, Klunk and Zilly), CB Bears, Undercover Elephant, Crazylegs and Blast-Off Buzzard, etc.), as well as producing non-Looney Tunes/Merrie Melodies TV shows such as Ruff and Reddy, The Flintstones, The Jetsons, Top Cat and Scooby-Doo.

Trivia

 * Due to Warner Bros. acquiring the character rights for Tom and Jerry, the Gene Deitch-directed shorts for Rembrandt Films ended up to be made in this alternate universe at Warner Bros. Cartoons by Hanna, Barbera, Jones, Freleng and McKimson, retaining the duo's original style.
 * Also, in this alternative universe, Jones was never fired from Warner Bros. and his Tom and Jerry shorts were made at DePatie-Freleng Enterprises.
 * All the crossover series with the HB animals in this alternative universe were put with the LT/MM animals added and are named after Bugs Bunny instead of Yogi Bear, such as:
 * Bugs' Gang
 * Bugs Bunny's Treasure Hunt (with Top Cat being replaced by Granny)
 * Yo Bugs!
 * Between 1986 and 2000, The Bugs Bunny Show was named The Bugs Bunny and Yogi Bear Show.
 * In Tiny Toon Adventures, some Acme Looniversity students with these characters as their mentors are:
 * Widdly Bear (voiced by Rob Paulsen) - Yogi Bear and Boo-Boo Bear's apprentice.
 * Sawyer Puppy (voiced by Frank Welker) - Huckleberry Hound's apprentice.
 * Toothy Tiger (voiced by Jess Harnell) - Snagglepuss' apprentice.
 * Tyler Kitten (voiced by Frank Welker) and Jessie Mouse (voiced by Tress MacNeille) - Tom and Jerry's apprentices.
 * Shooter McDavis (voiced by Charlie Adler and later by John Kassir) - Quick Draw McGraw's apprentice.
 * Daphne Puppy (voiced by Kath Soucie) - Droopy's apprentice.
 * Trickie (voiced by Frank Welker) and Trixie (voiced by Candi Milo) - Pixie and Dixie's apprentices.
 * Some of the characters appeared in /Harvey Birdman, Attorney at Law/.
 * In the Hanna and Barbera-directed Foghorn Leghorn cartoons, Foghorn is the winner instead of the Barnyard Dawg.
 * McWolf is usually an antagonist for various characters.
 * Unlike most MGM cartoons, Tom is able to speak, while Jerry remains silent.
 * In this reality, the Tom and Jerry, Droopy and Hanna-Barbera characters in The Looney Tunes Show have these changes:
 * Yogi, Boo-Boo, Cindy, Ranger Smith, Huck, Pixie & Dixie, Mr. Jinks, Tom, Jerry, Butch, Spike and Tyke, as well as Wile E. Coyote (who would be able to speak), live with Bugs, Daffy and Speedy.
 * Droopy is Porky's roommate.
 * Quick Draw McGraw and Baba Looey are famous entertainers.
 * McWolf is a recurring character, commonly adopting various aliases to fool Bugs, Daffy, Yogi, Boo-Boo and Cindy (ala The Red Guy from Cow and Chicken), but he is always arrested.
 * Dick Dastardly and his three henchmen Muttley, Klunk and Zilly are recurring villains.
