In this video, I replaced PSQ's Dragons Wings, without using Mutagen and without adding any other mods. In standard, PSQ uses Dragon Wings. Below, necessary mods, explanation for the replacement and demonstration video . This method is also applicable to Succubus Race, as it can transform  and fly

Mods used for this result:

XPMSE with HDT physics

PSQ +PSQ Transform Package Fomod : ( this addons necessary for folders meshes and textures ) .

Animated Dragon Wings AIO : During installation , set this to 100% . Mandatory for HDT wings

Fly mod + Fly mod overhaul patch : ( this addon prevents glitch ) Mandatory for fly

Animated Featherd Wings : this necessary for replace wings .

Evelynn Agony's Embrance : for change voice during the transformation .

1) Download the Animated featherd wings mod, extract the files. With OS choose the wings model you like from the meshes folder. In the video I used the Guardian model.

2) Rename the file. I used DragonBloody

3) Choose the textures to apply. ( I used the Guardian Red Textures ) , and rename them as follows: DragonBloody, DragonBloody_n, DragoonBlody_g

4) Replace the renamed files in the respective AntonMod meshes and textures folders.

5)With Nifskope, import the replaced meshes file: Skyrim data folder / meshes / [Anton] mods

6)Reapply the renamed textures you will find in the skyrim data folder / textures / [Anton] mods. They will be applied in the following order: DragonBloody, DragonBlody_n, DragonBloody_g

7) In game MCM / PSQ / Transform menu, active wings when transformed, select the Bloody from the menu, transform with the new wings.

? Download and extrat Evellyn Agony's , From the available folders, choose the audio you like best , rename the file with moans01 . Copiare/incollare in Skyrim data folder/Sound/fx/psq/fxTransform

9) With Additemmenu search Fly ring and read the Fly spell and fly configuration books . Player / spell menu, select fly spell (if you want to insert it in the favorites) and succubus transform (also insert it in the favorites) activate them in succession ( first the mutation, then the flight ) with the Key Z
Assign the number (for convenience use 1 and 2), Transform and fly.
With Fly configuration, you can also activate visual effects, I recommend selecting no stamina consumed, this will allow you to stay in flight practically forever, or until you decide to go down

Any other mod in the video is irrelevant to the result

Good flight
