I say that if they don't improve your comic, scrap them. I agree with others who suggest you can offer them as a bonus content for fans down the line. But it's not worth the time and effort to make something fit when it just doesn't.
When I started my comic, I was doing it traditionally; I got about 6 pages sketched out before I realized it's way more efficient time/money-wise to do it digital. It was a little annoying having to re-draw those pages, but they also looked a whole lot better because I was coming back to them with fresh eyes and a better understanding of my comic.
An important part of doing sequential art is being ok with throwing stuff out when it doesn't work. Think of the whole picture, rather than the time spent on bits and pieces. That time isn't truly wasted if it brought you closer to what you really want!
