Probably not.
If I'm not mistaken, back in the 3DS days, for installed versions of the game:
1. A small amount of data, akin to the checksum of the save is saved on the devices memory (nand)
2. The save is encrypted against console and stored on the SD card.
The point 1. is to prevent users from restoring an older save (for cloning etc)
The point 2. is to prevent users from sharing the save with other 3DS (once again for cloning reasons).
So even if you find the encrypted save in the SD card and know where to copy it to, the #1 would be incorrect, and it would force the game to restart.
of course, what I'm saying is based on your report on the OFW/emunand CFW save being disconnected.
Since I don't use emunand on Switch, I didn't know about that, and haven't read about that so far.
