Delete one instance of the files after sync (A to B, then B to C, delete B files)

Hello, I am duelbooting, and I have LUKS on my linux partition which makes it near impossible to mount and use without a lot of hacky solutions I don't want tot use. I want to use my raspberry pi to sync gamefiles and other massive files meant only to my laptop to it, then I want to reboot into a different OS, get those files synced on a different partition then have the original files on my pi be deleted, is this possible? is syncthing the best for this
