This is a silly idea.
SDT imports are effective insofar as a character has a unique and recognizable visual design. Bethesda doesn't really use hairstyles to establish or distinguish its characters - the studio relies much more heavily on costume, posture, animation, and voice acting. Hairstyles in TES and Fallout are copy-pasted onto dozens of different characters because "filling the world with NPCs" was much more important than "preserving the visual uniqueness of each character." The shading and physics applied to hair in Fallout 4 are very rudimentary. You're not supposed to be paying attention to it.
In addition, the Fallout games employ a specific visual style which differs sharply from the saturated-color anime presentation of SDT. When re-creating a Fallout design in SDT, many details would necessarily be altered or lost in translation. And you're starting with a design which is not especially interesting or distinctive. It's doubtful that anyone would be able to look at the result and say "hey - that's Nora!"
If you want to play out Fallout fantasies in SDT then you should be asking for vault suits, guns, backgrounds, and dialogues. Custom hairstyles would be a waste of effort.
