I think it would still be your own artwork, and it would be interesting since you could treat it like a very robust series. Lots of artists have done this successfully. Craig Drennen, for the last 4 years, has organized his studio practice around Shakespeare’s Timon of Athens, and for five years prior to that, he created work based on the movie Super Girl.
I say go for it, and do it for yourself.
I think my ideal commission right now would be to illustrate a volume of Hans Christian Anderson fairy tales. The thing is, I feel silly doing it myself, because my time is probably better spent working on my own artwork. So, who wants to hire me? :)
