Hacking GodMode9 and possibilities

[eworm]

I have recently discovered GodMode9, a (dangerously) powerful tool that has allowed me to change my Friend Code (A9LH + Luma).

Now I can't help but think what other magical things could be accomplished with a similar method of:
a) backing up the NAND via Hourglass9
b) using TinyFormat and setup the system from scratch
c) backing up a system save with GodMode9
d) restoring the NAND backup
e) injecting the post-format save with GodMode9

Would it be possible, for example, to backup a "NNID save" on one console and restore it on another, effectively having two consoles with access to the same account (for eShop, Pokémon Bank etc) or a single console with the capability to switch between accounts?

Would it be possible to setup a different region after the TinyFormat and backup/restore a "Region save", thus changing the region of the console without losing data?

Excuse me if any of that is a disgustingly obvious "no", I'm still way closer to a noob level than I'd rather be.

2 consoles can't have the same nnid. Something happens if they do.

I didn't change my friend code. The OP linked this so that might help.

Whoops complete fail. I didn't see the link nor mean to quote your post!

@eworm FYI that "something" is getting banned.

I attempted to do this same procedure but the only result that i obtained was that the system would prompt me to change the settings for the friends list. Does anyone know what to do in this case. N3dsxl 11.2.0-35U A9LH Luma
