There's already a section in 3DS.Guide that covers people who want to move their EmuNAND to SysNAND.Like you siad there are few reasons to use emunand, still there are people who updated to B9S 1.2 and still use emunand, who later on maybe want to switch there emunand to sysnand.
(I bet more and more emunand users will switch in the end)
So how to do? (this is in theory, so don't take me on it)
- Make an EmuNAND backup with GM9
- Go to \gm9out folder on your SD, select nand.bin and press A button
- NAND image options
- Restore SysNAND (safe)
In theory this should restore your EmuNAND backup to Sysnand and keeps your B9S intact?
Or do you need to do some preparation first to be sure B9S will still be there once you got rid of EmuNAND
For example:
- Do i first need to copy boot.firm to "EMUNAND CTRNAND" and Luma folder to "EMUNAND CTRNAND/rw" (Like we had to do to "SYSNAND CTRNAND)
- Then make an EmuNAND backup
- Then restore this NAND.bin to SysNAND

And it doesn't involve doing anything hacky like you mentioned in scenario 2, nor making a NAND backup of it, as mentioned in scenario 1.
