Scooby Doo! Meets Teenage Mutant Ninja Turtles

to me this could be a cool movie concept

Scooby Doo! (Warner Animation Group) (Cartoon Network)
Meets
Teenage Mutant Ninja Turtles (Nickelodeon) (Paramount)

since Scooby has had cross over movies before with the
Batman Justice League and half of other Cartoon Network
and DC Characters what if Scooby had Cross Over movies
with other characters from Nickelodeon starting with

Teenage Mutant Ninja Turtles
wondering how Scooby Shaggy Daphne Velma and Fred
would meet Leonardo Donatello Raphael and Michealangelo  
and Splinter April Casey

the storylines should be well written and fresh CGI 3D
Animation Designs

but convincing Warner Animation Group and Nickelodeon

may take time what do you think ?
