Replace a Follower Mod's visual appearance with another mod's?

[Yosharian]

I want to try out this mod:

 

Song of the Green

https://www.nexusmods.com/skyrim/mods/81921/

 

But I'm not a big fan of the visual appearance of the follower.  I was wondering how easy it would be to rip the appearance of another follower design, for example:

 

Lilu/Malu

Note that I don't want to simply replace the visual appearance of the follower with a vanilla appearance, but rather the appearance of a specific custom mod design (such as Lilu, or one of the BIJIN redesigns).

 

Is this possible, is it easy to do for a newbie, etc?

 

I have some limited capability with TES5Edit, so if I had a list of instructions like 'copy this line from this mod to this other one' I could probably do that.

 

Thanks for reading!

 

PS: I should clarify that I'm mainly interested in the face appearance, though if there's an easy way to customize body appearance as well, count me in.  (That said, I actually strongly dislike the... let's call it slightly unrealistic body that Lilu has, but that's a discussion for another time)

The easiest way would be to create her head by yourself in RaceMenu or ECE and than make a follower from a TES wiki tutorial.There are many "underwater stones" in copying or remodeling existing follower head meshes, even when you created and exported it in CK by yourself. You'll need to learn it yourself brother.

what does the blabla above have to do with his question?

 

install nifskope

open follower 1 head nif

open follower 2 head nif

rename follower 2 eye something to what there is in follower 1 head nif

same for the rest

rename follower 2 head nif to follower 1 head nif

overwite follower 1 with follower 2 nif

now follower 1 have follower 2 head in game

 

the only thing you need tesedit for, follower 1 have weight 80, follower 2 have weight 20, you have to give weight 20 to follower 1
