My idea for the ending

It could feature when Bugs, Daffy, Porky, Lola, Speedy, Taz, Elmer, Foghorn Leghorn, Gossamer, Marvin the Martian, Petunia Pig and Kayla teams up with The Powerpuff Girls and tries to defeat the Powerpunk Girls from destroying the earth, but when Tina recognize Daffy where their friends were trying to defeat Powerpunk Girls, and witnessed Daffy's swordfight with Berserk. After The Powerpunk Girls Defeat, Daffy dies, and Tina gives Daffy some healing medicine, after Daffy being alive now, Lola recognized that the Powerpuff Girls (including Kayla) would have a surprise, Lola could have children, maybe it could also be like that.
