That would be pretty easy.  Set rsync's verbosity/itemizing at an
appropriate level and then write a little script that parses its output
into a list of names of transferred files using grep and sed.  Append to
an exclude file.

What you're doing vaguely resembles half of two-way synchronization:
copy in one direction but keep local changes.  If new cases such as not
overwriting files modified on host B arise, consider using Unison or
even a version control system.
