I've thought about this for my comic; having shorter scenes act as interludes between the lengthier story chapters, because the scenes themselves might not actually fit(?). Though they could still enhance the world and characters, like a bonus scene or whatever.
So, yeah, I think this is a really neat idea you have! Though be careful of too much tonal whiplash if the strips are more light-hearted and the story is more serious. Then I would suggest separating the two.
