Well all those changes could be made:

Mithril could spawn only in Meneltarma and under the three Peaks of Khazad-Dûm and be made even more rarer. Therefore there would barely be enough Mithril on the map to make 10 pr 20 full Mithril equipements. Due to its rarity, Mithril should be totally unbreakable; furthermore, if thrown in lava, it couldn't be destroyed. The item should not despawn. If Mithril item(s) were to be thrown away, there could possibly spawn a small chest or a representation of the item on the ground. Thus, it would cause no problem in singleplayer, and, in multiplayer, Mithril would be really valuable, and you would have to kill a player to get mithril equipment once there doesn't remain any Mithril ore in the world.

If Mithril items were to be lost, there should be a command to to to the nearest Mithril item dropped on the floor, or something to prevent players from randomly dropping Mithril items, causing them to eventually be lost for eternity.

I doubt that everyone would enjoy, and I am not even sure if this idea is good, but it might add a bit of challenge to the game.
