Yeah that sounds okay.

The Velvet Keys thing is a bit unnecessary, and a rather cheap way to keep people not associated with the mirror world out.

I think we should have a place where people won't look twice...

Also even with wooden swords, you would still be approached by police. I would know. You're required to wrap it up, so I think anything is okay as long as you can wrap it up, or it doesn't look like a weapon, like a ball.
