Are you saying
  (1) you want to move the files from A to B on the destination
without having to retransfer them from scratch, or
  (2) you merely want to compare B on the source to A on the destination, or
  (3) something else?

For #1, you can move the files on the destination by hand and follow
up with an rsync to make sure any changes made to the source after the
original move take effect on the destination.  For #2, you can run
   rsync --dry-run --itemize-changes src/B/ dest/A/
to get a list of all the files that have changed between source B and
destination A.

If B on the source and A on the destination are the only directories
involved, you can just do something like:
    rsync -a src/B/ dest/A/
However, if you are also synchronizing other directories that have the
same name on both sides, I don't know of any rsync command that will
map these other directories unchanged while mapping B on the source to
A on the destination.  The best you could do in that case would be to
run rsync once from src/B/ to dest/A/ and again from src/ to dest/
with appropriate exclude filters.

(GNU tar recently gained a --transform=SED-SCRIPT option that will
make it transform filenames as it reads or writes an archive.  It
would be very cool if rsync offered a similar transformation step
between file scanning on the sender and the file list; that would
allow pretty much arbitrary mapping of directories.  However, enabling
this step would dramatically increase the sender's memory usage since
it would have to store two versions of each filename.)
