Voxel Character Automation Generation Programming

MagicaVoxel
I am looking to create a program in whatever the appropriate language is - java/python/ react or other, that can create a number of variations in voxel characters. The variables are as follows:

There are 'x' number of voxel characters (admin should be able to load new character shapes)

Each character shape is made up of voxels without any of the variables.

Each character can have a hex color or hex color gradient.

There are 7 variables for each character.

1. Eyes
2. Nose
3. Ears
4. Hair
5. Mouth.
6. Teeth
7. Accessory

Each of the 7 variables has 'x' number of options (admin defined to add/remove easily)

Each of the 7 variables can have a hex color or hex color gradient.

Each of the options is a number of voxels placed on top of or in the character's shape.

On running the script the program should generate 'x' number of unique voxel characters (x can be defined by a number by admin anywhere from 100 to 10,000)

I would start with 12 voxel animal character shapes with 10 options per variable each.

Thanks!
