No Idea if anyone has done this one or anything similar, but it popped into my mind and I thought it was awesome.
Name: Valkyrie (based on Ride of the Valkyries)
Type: Wearable stand

It's a very combat focused stand designed to fight off enemies and protect the user. Due to it being armor range is basically non-existent, but can detach up to a meter. Weapons can be thrown but will vanish after 5-8 meters max.
Weapons can be summoned separately even without the armor equipped, but will be much more difficult to use.
