Good point, I'd agree with the stipulation that it'd have to be a stock weapon.
Which does bring up the question of how do you get a drone to use a modified weapon?
Honestly, at this point I'm considering houseruling autosofts to be generic so that riggers can just pick up an Targeting: Automatics autosoft if they want to. Simplifies the unnecessarily (in my opinion) complex drone-only skill issues, and does away with situations like this. If you wanted to use an Ares Alpha to it's full potential you'd have to get both an Automatics and a Heavy Weapons Autosoft, but this would also give you the ability to use any automatic or heavy weapon available.

I honestly like that better.

Point of contention: a Rating 6 pilot is as intuitive and reactive as the very best of unmodified humans. I hardly think "a small child" is an apt analogy.
And second, how do you get 20+ dice on defense tests? These are not actions so you don't get RCC and hot-sim bonuses, which means you'd need a combined REA + INT of 14+ before full defense. Without full defense you're looking at 10 each for Reaction and Intuition just to get to 20.
Finally, by claiming that riggers shouldn't be running their drones on autopilot you are effectively removing a whole archetype. There are riggers who jump into their drones, and there are those who don't. Rigger 5.0 specifically describes both, and telling players that they shouldn't use autopilot to avoid losing money is, in my opinion, a terrible way of dealing with the inherent flaw of game balance where one poor dice roll for a drone rigger means thousands or even tens of thousands of nuyen gone forever.
I've said it before and I'll say it again; under the core (and Rigger 5.0) rules, I don't see riggers as being a viable archetype because they are too resource intensive for what they can do. Magicians and B&E types can more or fill the same roles on a team for much less risk of monetary loss if using the rules as written. And this is why my house rules for rigging is a couple pages long...
