I do this and it’s pretty smooth.
If you conflict by saving in both locations it will sync one as an alternate filename so you don’t lose anything and can resolve it manually.
I also run it on my NAS, and my NAS folder has versioned backup on it… So even if I do mess it up by deleting it, i can recover it.
My wealth and treasure? It can be yours if you want it! Search for it! I left everything in that one place.
