The userstore is a vfat partition, not sure that's even doable. Maybe with a bind mount, but I really don't know how it handles changing files. That's a nice idea though. But that still doesn't solve the issue of how the hell do we, out of framework, know when we switch booklet, and which book we're opening (Even sniffing the syslogs, I'm not sure there's enough info, if it's an amazon book, we get the ASIN, if it's not, we only get the filesize & timestamp). And even less how to pull the cover out of this book.
