you’d be one step closer than starting fresh, but ya there would still be a ton of work. You would also have to deal with changing the story presentation into something suitable for a visual medium because there’s a lot that works in a comic that won’t work as a novel (eg random flashbacks) and a lot that works in a novel that won’t work in a comic (eg characters thinking to themselves)
I don’t mean to make it sound intimidating or be like ONLY THE MOST WORTHY OF SOULS CAN STAND UP TO THE CHALLENGE THAT IS CREATING A COMIC. originally I just said it because it’s like the only useful thing that I could think of that not everyone already figured out lol;;
