How many of the Pokemon games do you have for the Nintendo Switch? Regardless of how many of them you've got, you can use Checkpoint to dump the saves to your SD card, put the SD card in your computer, and edit the saves with PKHex (if you have two or more of the Pokemon games for the Switch, just save each Pokemon you want to trade as an individual file so that you can copy them over to another game. They won't evolve this way though). But yeah, if you unblocked Nintendo's servers and went online on your hacked Switch, you definitely are at risk of getting banned, so if I were you, I'd keep Nintendo's servers blocked.
