Scooby Doo - Thomas and Friends style

Plot
I remember Scooby Doo episodes. And I think they're awsome. One of them is when Shaggy is roller skating and crashed into the bath tub. I remember that episode so much, Shaggy and Scooby Doo are almost identical to Thomas and Percy.

I remember one of the Thomas & Friends episodes, Percy is frightened by Gordon and his express, also Scooby Doo is scared by ghosts and chased. And as for Thomas and Shaggy, their personalities are silimar, because they're both teenagers.

For the rest of the gang, I would like to make engines match: Fred was the bravest (so Duck matches it perfectly), Velma was the smart girl (so Emily is the perfect candidate) and Daphane was the pretty girl (so Rosie matches it too).
