Trial chamber loot suggestion Crossbow attachment

The loot in the trial chambers currently is a bit unimpressive. As the theme for the update includes Tinkering in addition to trials, I think it would be nice if you could find something that allows for tinkering with your weapons in the chambers. Therefore, I suggest adding a crossbow attachment holder item to the trial chambers loot table, which could be used in crafting recipes to add additional features to your crossbow (perhaps using the fletching table to switch attachments?)

One such attachment could be adding a spyglass in the recipe to give the crossbow a "scope", adding spyglass functionality to assist with aiming crossbow shots.
Another attachment you could give your crossbow could provide the ability to charge up a second (or maybe more?) shots that could be released in quick succession, perhaps using a bow for the additional crafting ingredient.
I am sure there are even more interesting modifications that could be implemented with such an attachment holder that I haven't thought of yet.
