Syncthing + Rclone + Fuser Mount + Team Drive

Would it be possible to use the syncthing + rclone + fusermount + google team drive set? The idea was to mount a folder with fusermount + team drive (unlimited space) and use rclone to put the backup syncthing files into this folder

As long as all of the involved things manipulate files or represent themselves as files it sounds doable. I have my Documents directory in iCloud and also synced by syncthing, which sounds like something similar to what you want to do.
