More artillery-like weapons

[pra]

Just had this idea: would it be possible to add new artilleries? AKA, new buildable objects which will react to artillery grenades and fire different projectiles at the target location. For example, a nuke artillery which fires mini nukes, or an artillery which fires a lot of small projectiles instead of one large, or even a laser artillery, with the explanation that there is a pre-war mirror satellite in orbit, on which the beam is reflected, with a similar effect to the archimedes death laser from new vegas.

 

Or, at least, automatic artillery pieces, which do not need to be manned, only powered.
