Then there's still the issue of my NNID...but I've already thrown so much out there. Sorry for all the clutter. I'm kinda thinking out loud, so to speak.
The system transfer will move your NNID, and it will make the target system be able to use the data stored on the sd card in this directory: /Nintendo 3DS/ if you have frshp software in there, you could "reavtivate" this software on a hacked system by reinstalling the corresponding tickets. Only proper tickets bound to your NNID/eShop get moved.
You cannot move this folder and use the software in /Nintendo 3DS/ on another system without a system transfer.
I would honestly not bother with it, since saves are no big deal when you can use JKSV/JKSM and if I wouldn't have any important purchases and/or friend codes registered.
Your pre installed game can be reinstalled using a proper ticket too so you don't lose that.
You can also use one sd card for multiple systems, the 3DS will create a folder for each device that only this one system can access.
