Unfortunately it's hard to get items in (other than maybe TFs) for most people, since the submission rules pretty much say no items. Obviously this doesn't apply to the main devs and writers, but they're focused on more story and characters in most cases. For anyone else submitting, you'd at the very least need to make an NPC combatant to have the item drop or write a small dungeon/quest (which is more work). Otherwise they'd be swamped with submissions for items. I could certainly make Facebighter, the Katana of Hellish Torment a versatile (one or two hand) corruption weapon, but being a katana, would likely involve kitsune (probably Takahiro uncovering it while out hunting Keros artifacts) and a dungeon, or a Will-o'-the-Witch set for Vivianne (non-demon) that looks like a virginal white robe and glows with luminous light and releases blinding flashes during combat, but that would likely require at least a fetch quest for items.
High-heels are definitely doable (and this is the forum for posting wishes), but unless the main writers do it, any other submitters need to add surrounded content at the very least, which is more work when you just want some kinky boots.
