Adult animation

Want to create animation of several episodes of little rascals old black and white shorts but using different characters to not invoke any copyright issues. (will be done in color) Episodes to be recreated are "Too Too Young" Choo Choo" and Canned Fishing" I only want to create small parts of the episodes not the entire episode. I will go into more detail after first contact. They will be of an adult nature. Similar to the adult cartoons I have seen on the internet of popular animated TV shows. but in Animation not comic strip type work.
