rsync is not interested in your short or empty files, but you may be able to ask it to not sync large files, let's look:
https://www.unix.com/man-page/linux/1/rsync/ Yes:
--max-size=SIZE don't transfer any file larger than SIZE
Now, for the big files, you need to script up a find and process to make the exerp or empty files under the right relative paths.
If you make a local clone tree of the original directory tree, modified with exerpts, you can rsync that all, so your script does not have to ssh for every file it creates. A clone tree is a dir on the same device where you make all the same sub-directories and then hard-link all the files of the original tree (and any other inodes including any relative withing subtree symbolic links, but not absolute or relative outside subtree symolic links). When you want a file to be different, you must delete the hard link and replace it with a new, real file. (Only such files, with one link, should be written, else you destroy the original.)

Name
rmf - remove folder
Syntax
rmf [ +folder ] [ -help ] [ -[no]interactive ]
Description
The command removes all of the messages within the current folder, and then removes the folder itself. If there are any files within the
folder which are not part of MH, they are not removed, and an error message is displayed.
You can specify a folder other than the current folder by using the +folder argument. If you do not specify a folder, and cannot find the
current folder, asks you whether you want to delete instead.
If the current folder is removed, it makes current.
Note that the command irreversibly deletes messages that do not have other links, so use it with caution.
If the folder being removed is a sub-folder, the parent folder becomes the new current folder, and tells you that this has happened. This
provides an easy mechanism for selecting a set of messages, operating on the list, then removing the list and returning to the current
folder from which the list was extracted.
Using to delete a read-only folder deletes the private sequence and current message information from the file, without affecting the folder
itself. If you have sub-folders within a folder, you must delete all the sub-folders before you can delete the folder itself.
Options
-help Prints a list of the valid options to this command.
-interactive
-nointeractive
Asks for confirmation before deleting a folder. By default, deletes a folder and its messages without asking for confirmation.
If you specify the -interactive option, asks if you are sure before deleting the folder. You are advised to use this option,
since when deletes a folder its contents are lost irretrievably.
Examples
This example shows how asks for confirmation when the -interactive option is used:
% rmf -interactive +test
Remove folder "test"? y
