Spyglass update

Just had this crazy idea-what if we could stack spyglasses (no, not in the inventory). What if we could arrange them diagonally in the crafting table grid and get a stacked spyglass? The stacked spyglass could zoom in more obviously, and also can be taken apart when put in a crafting grid to give ypu the number you stacked. And in case you don't know what I'm talking about, it's literally putting one spyglass on top of another to zoom in.

2nd idea- since spyglasses are copper, they should oxidise over time. Like, the lens becoming fogged and the yellow and brown changing to turquoise and green. Maybe they could also not be able to zoom in that much anymore. You have to clean it like a copper bulb.
