As for Stormbringer, I'm not sure it'll ever happen. I'm going to be tied up with Coxville Curse 3 for a long time releasing it in increments. If Kaos expresses interest I might do it as a comic script and convert it into a story later. My idea would be to tell the story of how Flex took these new women, but like anon mentioned wanting to see more Marisa, she is one of my favorite female characters and I'd love to see her again. I love the hyper lactation angle. Maybe a split story would be feasible. I did sketch out ideas for a story that I thought would make a great prequel to Flex featuring how his wife first found out about his impregnation obsession.
As for Kaos, she might be interested if she gets enough requests. The best way to do that is to tweet her (I think it's @kaoscomics). I also think there's an email contact on her home page. It could come down to how much free time she has. As far as I know she's finished Son's Best Friend's Dad, Wife and Gardener's 2&3, and some of the Flag Girls which will be bigger then Flex. I've also submitted Doctor Bitch to her and another author is apparently working with her on a couple stories. If there's anything else of mine, you'd like her to do feel free to contact her. Your other best bet for seeing something of mine illustrated would be blacknwhitecomics.com. Also, it's always nice to show your support by joining her site as www.kaoscomics.com She's a hard working artist and deserves to be paid for her efforts. She's also one of the most reasonable paysites I work with even running $10 per month for life monthly specials.
