Only question is what to do for gunner's weapon. A support weapon would make the most sense, but an actual minigun would step on HMG's toes too much. The heavy autocannon could be an autocannon variant that functions like a weaker/rapid fire one similar to the autocannon mech, but that already exists in the game in a latter sense. The rocket launcher could be fun if it works like one of its overclocks in that you charge up to fire more rockets, but I personally think just having his coil gun as a secondary charge weapon/railgun might be best even if underwhelming.
