[Help] How to turn an unnamed NPC into a "named" one

[tentaclemight]

Imagine you are killing some bandits or vampires, i.e., NPCs that are not unique/that respawn, and you come across a particular one that you want to have as a follower for any kind of purpose, be it for marriage, for detailed study of its anatomy, etc
How do you do it? Is there a mod to do that?

 

 

They way I kind of figured (flawed), is as follows:

 

While approaching Valtheim Towers, I was asked to pay the toll by a female Bandit. I don't know if it was the way she asked me to pay the toll or something else, but my PC knew it was lust at first sight, so I paid her the toll so that she wouldn't become hostile, and placed a mind control circlet on her inventory, which makes her a controllable NPC. (This was actually my 2nd approach because I tried to use ATF on her immediately after paying the toll. However, her dialogue would be restricted to the dialogue options ATF provides, so no SexLab dialogues, for instance...) Back to the story, in order to see if I had sucessfuly convert an unnamed NPC into named one (or at least an unnamed one with named ones' characteristics), I decided to try Hentai Pregnancy on her because this mod works differently whether you use it with named NPCs and unnamed NPCs - named ones get pregnant (and appear on a list on MCM) and unnamed ones simply get "cum inflation" that disappears when you travel to a different cell (and also don't show up on the pregancies list on MCM). So I did the deed then traveled to Whiterun, and the said NPC presented an unnamed one's behaviour - cum infation and not listed on the list.

 

This result, raised more questions - if I remove the circlet or when using strictly ATF to control her and then dismiss her as follower, what will happen? Will she just be reabsorbed by the generic npcs engine or something like that, and disapear? One good thing about that circlet is that the NPC "will become essential after wearing the circlet long enough", and by essential it means " In effect, this means they cannot be killed under any condition, and when their health bar fully depletes, they will merely fall into a state of recovery before reverting to normal again with full health" (http://www.uesp.net/wiki/Skyrim:Essential_NPCs), yet I don't know if that doesn't stop her from going back to the Valtheim Towers and/or just become an immortal and agressive Bandit.
