It has been repeatedly brought up that the spire's pointy thing could be a sword of Damocles, hanging above for a chute vent goomba stomp.
This got nixed because there's no use for it. But think for just a second. It doesn't need to hit only while going down. Make it into a keel blade-like device, where you can hydrogen juke a ramming pyramidion just enough to let the bottom bit of that spire just smash through the enemy ship.
That would add an entirely different dimension to fighting a spire. You not only have to worry about the tri/quadrafecta of guns, but also beware getting counter-rammed (or even rammed muahahaha) by it.
