It's good that you bring this up, but I don't think it will be a
problem.  The --min-size and --max-size options tell rsync to skip
transferring regular files whose sizes are out of range, but those
files are still present in the file list.  Thus, the receiver will
know not to delete any of the files from the "Current" dir that exist
on the sender, even files that belong to the other pass.  The two
passes should give you the same result as the one pass currently does.
