Hmmm, perhaps it is considered a glitch by the developers if it was not planned for, but to me it makes sense in the realm of physics at least.
I mean, your idea isn't bad at all in fact it's a good idea, I think you are the first to think about it perhaps, i'm just trying to think of what immediately sounds good and bad about it to me personally. It's nice to see people stay encouraged to keep brainstorming.
It would be nice to freely shoot, however at the same time you are making it easier, to me it feels like giving weightlifters bionic legs or something lol, taking away the need to control themselves efficiently and eliminating the risk of damage due to a lack of using the proper technique.
Also, with phased worms/weapons it would affect turns where you and your opponent are piled. It is commonly known this game is "pixel perfect" in the physics, so if we can place/shoot weapons inside/through our own worms but not the enemies, i'm sure this would have an effect on piled worms.
Even for example you shoot a zook with extremely high wind, it hugs the landscape, it passes through your worm, travels a bit more, hits the enemy worm, that shot SHOULD have hit your worm...
The 2 main things here for me would be:
Pro - More shots become available - I always love the option of having a larger variety of possible shots!
Con - More shots become available - Normally a good thing BUT, it is in a way that eliminates an existing skill and the experience it takes to recognize it's use.
Con - This would affect techniques dealing with piled worms, and make it possible to shoot through your own worms.
If you can find a way to add something to the scheme, without eliminating a common skill, or having situations that should have hit you but hit the enemy instead, that would be great!
Keep in mind, this is just my subjective opinion, other people might look at this as a blessing.
