When Has this not been done? Of course we call it Homage. Do what ever you want and let the pieces fall were they may. All great artists copy or have copied, changing a little here or alot there. And I have seen it done here with some great painters ie Escher, Botticelli, Rockwell, should I go on? Funny or not these artist have all been paid "Homage to" I guess you should wait till they are dead ;)or learn to take a poke. Remind me to have you by me that beer when mess with me }:)
