I would totally love to see that! And honestly, we had a few studios contact us over the years who were interested in the series. In the long run, all of them came to the conclusion that the series was too epic and too many characters. Still, one day maybe it will happen.
As far as collecting them into graphic novel format, I assume that you mean the colorized versions since the originals were only released as graphic novels. We would love to release the colorized issues as a trade, but we don't have plans for it at the moment. I'd actually love to do a limited edition hardcover collection of the colorized books.
