A file has one and only one inode, so that's not feasible. However the
idea of "editing" the inode contents (and the inode's blocklist or
bitmap) to make this work could be done in principle. In practice it
looks really hairy, and highly dependant on specific implementation
details of each type of filesystem. I've never heard of this being done,
but who knows?

Why do you need this? If it's for some special data-processing
application, would it not be easier to modify the app so it could
process a sequence of files?
