No, it's just not that simple. It's not a question of what readers are capable of. It's multiple universal standards that would have to change, and for what? Packaging has a bad enough time with UPS codes getting distorted to the point of being unreadable, and that would be even worse with 2D codes. Furthermore, 2D codes take longer to decode. 1D scanners are able to scan the entire surface of an object to find the codes quickly, or even two surfaces at the same time. Think cashiers again, quickly plowing through a cartload of merchandise. They don't have to aim to do that. They just have to know what side the barcode is on. It's a non-trivial engineering issue to make 2D as efficient to scan as 1D. There is absolutely no reason to move to 2D codes for the majority of existing 2D applications.
