Hacking About Nintendo Network Account in a hacked console

[Engi]

I have a Wii U that I plan to hack after nintendo moving to the switch. However, I have a nintendo network account with a lot of games, and I want to know how to hack it while having a way to restore it to its original state when needed for account transfer.

With what we got now, how could this be done? Is there a way already? How you guys have dealt with this issue?

Thanks in advance.

To make this short:
- restoring to original state: next to impossible at the moment, there will be a lot of leftover ticket files at least (and it'd be a lot of work)
- original state needed for account transfer to Switch: unknown (your Wii U games are linked to your NNID, unlike on Wii)
- possibility of account transfer from to Switch: speculative

I haven't thought about it. If I "lose" 200€ of eShop purchases over using Wii U backups, that's probably a worthy risk. They're still on the Wii U, after all.
