When I saw the MV generator,I knew that day would be close.
Now behold, for that day has arrived, thanks to Saint @Schlangan!!!
So as I'm in a sharing is caring state of mind lately, Here goes a small tuto on how to use Schlangan Extended Generator with PV.
First of all,
Download Schlangan’s Generator, and praise @Schlangan
Launch directly the exe file > a folder “resources” will be generated at the same path. (for convenience I dedicated a folder in my Game Dev directory to it)
On the upper left, click on assets, select > Manage Assets
Template Tab:
You will now need to create a series of templates corresponding to the dimensions of various PV sheets. I will only use the master sheet, the bust 1, the face and the paper doll files.
Mastersheet: 3072x3072
Bust: 512x512
Face: 576x288
Paperdoll: 512x512
Use the X and Y values to reposition the different Templates in the main window.
Edit: added after understanding how to recolor
As we do not have mask file, make sure you create the template with the color type option files selected.

Categories Tab:
Create 2 categories: Male and Female (always click on Update category Data).
In the Parts section, create the following Parts (you might need to add other parts, like coats, or armors for example, depending on how you want to use your resources).
Shadow, Body, Feet, Bottom, Top, Gloves, Hair, Facial Hair, Head, Accessory, Weapon
Make sure to fill the Name, Key, and use the “add a subpart”. Make sure to click on “update Part data”.
Now for the Male and Female categories, Check the box for each part needed.

Priorities Tab:
Make sure to setup the relevant subparts for each Template. Be careful to the order as it will determine the drawing layer order.
Edit: added after understanding how to recolor
as we selected a color type of files, we need to click on add new mask, it will add a Mask color as below
Resources Tab:
Now here comes the meaty part, which will take time.
For each of our individual resources, we need to setup resource Data.
Click on add new Resource
Give it a name, slect the Category and corresponding part.
Select an Icon (Guess what, you can use the Paperdoll file as an Icon)
In the file per template section, select the Template, click on Add, then in File Information, set the subpart, and Import the Resource file. Click on update data.
Edit: added after understanding coloring:
Make sure you select a Mask color when validating the part for each template. If you leave it on None, you won't bee able to use the color options
Once the 4 files for the 4 templates updated, click on Update resource/name/category/part.
Voila, one of your parts is in, Now Rinse and repeat for each PV resource you need, and enjoy an MV style generator working with PV resources!
this is how it looks for male bodies (what I have done so far) @Jesse - PVGames, let me know if the image below isn't modified enough to allow posting.

Hope you like it, Give it a try and if you find other trick for it, or find out the deal with the mask, please share.
Edit:
If setup correctly, you will even be able to change the colors, as the example below where a simple click allowed me to change the Bottom 1 color from grey to Yellow.
If at some point in the process you get an error message referring to a missing gradient.png file, copy and paste the gradient.png file from your Maker MV generator folder
Standalone should be: C:\Program Files (x86)\KADOKAWA\RPGMV\Generator (Could differ if you installed it somewhere else than default location, but in that case, well search for it on your PC)
Steam Should be: C:\Program Files (x86)\Steam\SteamApps\common\RPG Maker MV\Generator
