Yeah probably. But these aren't just "What weapons do you use", this is "Starting Combat Style".
Starting Combat style for Gunner is Long range, at the back, either sniping other gunners or trying to take down the enemy before they get to you. That suggests it would lend itself to evolving closer to something Akin to Funnel-spam, Heightened stealth to allow for ambush sniping, Combat analysis, Heavy artillery, ect. Hand to hand murderblender (weapons optional) doesn't seem likely to arise from that - perhaps not impossible, but far less likely.
