While an interesting thought experiment or possibly a test of your own technological prowess, my own opinion is that this doorknob kinda misses the mark in why we love guns and lands in the outer rings in simply having the shape of a gun.
Point of fact is that pulling the trigger opens the door in this doorknob. While that may seem cute, it completely ignores all the importance we place on trigger (and also muzzle) awareness and basically brushes aside the near religious importance we place on gun safety as enthusiasts. This doorknob design frankly belittles gun safety.
I’m not sure what could be done to address that problem inherent in your design. But if your intent was to intimidate anyone visiting your front door, maybe this doorknob actually fits the bill.
