Halls of the Grandmasters type map but for items

In light of recent events I would suggest making a new map available for standard mode, similar to the Halls of the Grandmasters which would let players visit displays of items from the past, items which were insane to craft and unavailable anymore. (and most likely unavailable before because of the costs)

The catch is that I would love to see GGG implement such a thing where these items are trapped in cases like in heists, but these cannot be broken. Instead they could be made interactable like chests but only a Mirror of Kalandra could be used on them to get a copy of them.

It would be a lovely way to make those items available to anyone with mirrors, free of charge :)

I do not play standard so if there is something I miss that might negatively impact the community, I apologize.
