Sadly, I don't know of any alternatives, short of coming up with a custom solution. I tend to like Jekyll for this type of thing, even though Jekyll isn't ideal either, because it also seems to be primarily oriented towards blogging or textual content. However it would be easy to create a comic-type post and a text-based posts template or separate the blog content completely from the main/comic content (which isn't "posts" anyway); you can do the same in WordPress, but it does require more hacking and wouldn't feel as "natural," IMO.
