I think it has been considered:

https://github.com/syncthing/syncthing/issues/109

https://www.bountysource.com/issues/1474343-support-for-file...

https://forum.syncthing.net/t/encryption-for-remote-syncthin...

Unfortunately there doesn't seem to have been much movement towards making it a feature.
