Like a MagnaGuard? If you’re doing that, why not just purchase lots of skill ranks in Gunnery for the droid?

And I wonder what would happen if the droid and the brain got into an argument over what they were going to shoot and how?

Just buy Assassin Droids and call it a day...

IMO, the IG-100 MagnaGuard is more deadly and more dangerous than any other known Assassin Droid in the Universe, at least with regards to its own capabilities.

If an IG-100 took over a droid factory and replicated itself into each unit that was made, the Universe would now be populated exclusively by IG-100s, and it wouldn’t have been a “droid revolution” or a “droid war”, it would have been a simple slaughter of all organic sentient life.

Fortunately, IG-88A wasn’t quite as capable as an IG-100 would have been, and so that disaster was averted.

True, but Assassin Droids have 3 Agi and 5 Gunnery.... I was just talking about operating guns on the Gozanti.

However, Droid brains are significantly cheaper and, with an Advanced Targeting Array, can do some significant damage on their own due to the wonky mechanics of hitting in this system.

And the reason one would need a separate brain for each weapon system is the action economy. It would make sense that brains would only have one action/round, irrespective of how many weapon systems they'd have access to.
