I really like this idea, and I feel it wouldn't be hard for Kane to create.
I think all he would have to do is take a Vendor contract and tinker with it:
1) Change the character model into an armor rack, and grant it it's own paper doll features.
2) Give it a reasonable gold sink moderate price. (After all we can have 50 vendors per house slot)
3) ... ??
Anyways, I have more incite on this, but would rather talk to Kane about it to see what he thinks.
PM me if you want to hear my ideas. Otherwise have a great day.
