First of all.... Never discount your talent or what other people see in what you've created. What we create speaks to people in different ways. There are plenty of (famous) artists I look at, visual, musical etc. and I think "meh" and then there are the ones who touch me and draw me in. So, take a tad bit of scolding from an old fart... never sell yourself short.
Lecture done... onward
As an novelist I can't fully answer your question so I'm hoping other comicfolk get on your post for a good discussion and can help you out in exploring this to see if it's viable for you.
Best of luck.
