Shaped Voxel Damage

[Context]

There are a number of reasons I believe having unique damage shapes for different weapons would be useful. For one, it would be another tool to ensure the meta for combat is not so restricted, allowing for an increased variation in viable tactics, and this is the initial thought process which spawned the idea. The attached picture is by no means even my preferred end goal of having shaped voxel damage, merely to introduce the concept of what is possible. Better then the simple graphic example, we would even have adjusted shapes based on ammo type, though generally aligned with a general shape. As per usual I will likely have to come back and explain further so I will be lazy and not attempt to pre-explain some wild tangents some responses will go down.
