Rocket Cart vs Onager?

I hope the rocket cart does something similar to this concet i posted some time ago:

Theoretical study of a Mangonel rework with 7 main Projectiles hitting in a hexagonal Pattern

Deriving from the Design of the Dromon I asked myself what would happen if the Mangonels would be changed similarly. The main Critique for the Mangonel always was that it showed several projectiles but only one of them did the vast majority of the damage. Whilst the Dromono shoots 4 Projectiles for the Mangonel I would rather prefer 7, as they can be layed out in a hexagonal Pattern which leads to more consistancy and continuity in the Damage output. The main Reason for that is that in a hexagon…

Would be a great chance to implement a tweak like this.
