Instead of NPCs selling cool-looking vanity equipment...

CRAFTERS should be able to make it!

NPCs already sell so much junk in this game that half of the economy is pointless and boring.

Crafting really needs more to it to justify the time, effort, and money that goes into leveling it. Housing items and vanity gear is perfect for this. There could be more recipes for interesting and unique armor and weapon skins, of varying levels and difficulty, but make sure to have some EXTRA cool/exotic-looking stuff with really challenging recipes at high DoH levels. This will make crafting, the economy, and the vanity system loads more exciting.
