Oh!
I really thought I saw something like text2layers one day. But I guess it was a dream. There´s the
create 3D text but I don´t know if it could help you.
This other one breaks the paragraphs into layers. But again I don´t really know if it would help you. Just another shot.

Hope you can find one that suits your needs somewhere.
Good luck!
