A Simple House Rule for Recovering Thrown Weapons

Yes, another house rule for dealing with the issue of not loosing thrown weapons. (Sorry if this exact rule was covered before... I have seen this topic come up a number of times on Ye Olde Inn and on Old Scratch, that I forget who covers what and when.)
The rule is simple, if your Hero throws a Dagger, Hand Axe or Spear, you (as the player) drop a weapon token in the room or corridor the target is in. Once all the monsters in sight are defeated, you may recover all discarded tokens with a simple search action. Should the Heroes move out of sight from where the items were thrown, they are lost... Forever! (The Goblin Janitor swept them up — where do you think the bodies and gear of all the defeated monsters go?) The result would be that other Heroes can pickup and use other Hero's weapons, but items maybe passed between Heroes as a free action.
A weapon token could be a full-sized tiles or half-inch counters. With the UK set, you only need one Hand Axe or Spear Token per Equipment Card. With the US set, you'll need at least a dozen Dagger Tokens. If you are using a combined weapon set unbound by Equipment Cards, then you'll need about: x12 Dagger Tokens, x6 Hand Axe Tokens, and x6 Spear Tokens. (It is assumed that some Heroes, like the Wizard would pile on more Daggers then normal, and that on average, each Hero would carry three Daggers. And it is assumed that of the three Heroes able to use Hand Axes and Spears, that they would on average, carry two of each.)
If you want to add ammunition to the game, you'll have to figure out how the total capacity of a quiver (accounting for any special skills or items that can boost this) and times it by three. So if you (as the Evil Wizard Player) rule that the Crossbow only allows for 10 shots per Quest (not an issue, as you can reuse them in the same Quest), 15 with the Big Quiver upgrade, or x2 with the Wristband of Lorien artifact (an item I just made up for this), you'll have to make 60 Bolt Tokens (15 for two normal upgraded quivers, and 30 for the artifact upgrade). As I just noted, you'll have to recover all your lost ammo with a search action, and should you move out of sight from your ammo, they are lost for good. If you loose ammo, you'll have to buy more to refill your quiver (the cost of which is up to the EWP). In a games like D&D, you normally have to cross out the number of arrows and stones you just used, but the use of tokens make keeping track of ammo a whole lot easier.
So what do you guys think?
