Will it be possible in theory to backup my saved games from my 5.0 Switch and use them on my 3.0 Switch (with another user account) ?
Theoretically yes, unless the games were played on different title updates - that could get messy. I was forced into picking up an updated cart of MK8 due to an update being flagged on my save whilst using a friends cart. But the update available then was still a favourable one.
To do so you'd either need to update the game without updating the system - As of now its difficult/not accomplished as of yet (I'm un sure if using the local update feature updates the system as well - research that) or editing the game save.
