[Poll] Idea of Patreon exclusive content? (Patreon)

Hello everyone!

I was thinking here about somethings that maybe could be appreciated by you, our supporters, and I came up with an idea. But I'm not sure if I should make it an exclusive content or not.

I was thinking about exclusive content to the character customisation where you would be able to select different character presets. The body-shape can't change for equipment slot reasons, but maybe we can make that you would be able to select the face and the skin of some of the unique NPCs we have, like Akrasiel, Merishya, Natasha and Kylira. What do you think about this feature? Do you think it's a good idea to make it Patron-Exclusive or not? 

What would be the exclusive thing for each character?

So far I haven't thought about any gameplay effect on it because it would be overcomplicated and could stimulate people to pirate the Patreon content. So I rather avoid it.

Kalyskah: Vampire fangs, the straight hair that covers some of her forehead (default one). Her muscular thighs. Some armours like the female-acolyte ones have the purple or other colourful parts turning red when she equips them.

Kylira: Bright glowing eyes, her slim elven face. If you add the elven morph on top of her normal elven ears, they would get really big! 

Akrasiel: Eyes without pupils, the wavy hair that is split on the side instead of in the middle, natural pale skin... And maybe wings in the future?

Merishya: Horns, tail, the hair with a fringe that is open where the horns are coming out.

Natasha: Her exclusive makeup and tattoos.

Rosália: Her scars, also have fangs (She is not in the game yet, but will be soon in gallery mode).

What makes me scared of moving forward with this being exclusive is the idea of having a "paywall" on the game... Something that I'm usually very against. But on the other hand, a cosmetic feature like that might be harmless and can be a nice way to thank you all and to give you something special for supporting us. Let me know your thoughts.
