I’m not a manga fan/consumer, so I may be a bit confused, but…are you simply talking about using a drawn image as a memory palace? If so, in that sense, I don’t think an art-filled frame from a manga (or any comic/illustration/art) would be any different than using a single painting from a museum, which has been discussed at length here. My extremely limited experience with manga makes me think it might be difficult to find images complex enough to yield a good number of potential locations—the art I’ve seen appeared to be very simplistic—but I could be wildly mistaken.
Unless I’m mistaken regarding what you’re considering, you may find some helpful information in these discussions:
