If there were some simple way for user code to recognize the end of an
archive, maybe you could interpose an input filter using
Boost.Iostreams. The filter would present EOF to its caller on
spotting the end of archive, but leave the underlying file open (with
its read pointer adjusted to immediately after the end of archive) for
the application to bind another instance of the same filter onto the
same underlying file.

Maybe you could derive an archive type yourself from one of the
existing ones that differs only in appending an easily-recognizable
marker when finished writing?
