Interesting. You might want to check in with Intrepid, a fan film series based after Nemesis. They might like to work with you in using their characters as a first effort for you.
Also, I've seen online comics at StarTrekAnimated.com. They're done with stills from the Animated Series like back in the 1970s, and they're a good read besides. That might be a good place to see how someone else did the online comics thing.
Keep us informed as to how the project is doing.
