Hello, are you planning to add cannons bigger tan 1 block in diameter? It'd be so fun to build something comically large, that's not practical, takes ages to reload and aim but has like a 2x2 chunks of splash radius. It would expand on the spirit of the mod (create BIG cannons duh) and would be a milestone to build in survival. Thinking about 2x2 cannons, they should be less practical than 1x1 cannons, more of a intimidation/for fun thing, so here's some suggestions to balance them.

• because the volume scales more with size, they would take a lot more metal to cast, they would still give most of it back after drilling it, but initial investment would be a lot bigger
• barrels will have less durability, so you won't be able to build it as long as 1x1 cannon with same material
• of cource, you'll need a lot more stress units to aim it, or it would only be aimable by installing it on a train, and controlling yaw would only be possible by building rails in the direction you want it to face and driving it there. (just like dora nannon)
• solid shots, like armour piersing, need to be casted. They will behave exactly like 1x1 cannons, so breaking them will only drop some material and would render them useless, so they'll need to be transported from where they were cast to the cannon by pistons/trains/assemblies on minecarts, the same way you transport 1x1 cannons.
  More simple shells can be just built by player or assemblers.

I've added screenshots on how, in my opinion, cartriges for 2x2 cannons could look.
(Netherite blocks are solid cannonball, that should be cast. Canister can be implemented separately, like casting with copper, or as i showed in my screenshot. TNT is used as a placeholder for propellant, I think adding seperate propellant charges for bigger cannons would be nice, something like pressing them in cauldron seems cool.)

What are your thoughts on this?
