What if Looney Tunes shorts lasted into the 1970's

Yes. Another AU idea of a popular cartoon studio who somehow manages to outlive further than it's expected close and keep releasing their cartoons, this time with well-known Warner Bros Cartoons and its wikipedia:Looney Tunes and wikipedia:Merrie Melodies series.

History
The Looney Tunes series was expected to end around 1963, but after request to extra cartoons, WB produced more, but those were outsourced to another studio with its main characters now being Wile E and Road Runner, Daffy now paired with Speedy. Even if that period went weak, it manages into 1967 when WB reopen their cartoon studio, and thus new characters were created. 1969 comes with a true feeling the studio will be closed, but contraring all expections, the studio manages to survive well for more 5 years or more.

General
Characters like Cool Cat and Merlin Mouse were retired, so new ones were created. The Abstract W7 was kept until the mid-1970, where it was replaced with the Kinney Shield. Even thought WB reinstaled the Classic Shield when it was sold to Warner Communications, the Kinney Shield was kept until the end of 1972. 1973 marks the usage of the W circle at the start and end of the shorts.
