Higher tiers with merch? (Patreon)

I don't know if I just unlocked this or if this is now a site wide thing, but I have access to the patreon merch stuff. I can set up higher tiers that would basically give you merch after 3 months of support (think it's a one time thing).

Here you can see what is currently available and the recommendation tier costs, toward the bottom.

Is this something you would be interested in? If so, I would be designing something exclusive for the merch. I can't include any copyrighted characters, and it would need to be rated for everyone meaning no omorashi. As for diapers, not entirely sure. I think I could probably get away with it, but no promises there.

Patreon would take 3% of what I make per month if I start doing this, so I would need to see quite a bit of interest for it. Don't want to sign up and then have no one ever go to that tier XD.
