As a Skull Merchant main that doesn't 3 gen, here's some changes that would help combat 3 genning.
Firstly, Geographical Readout should be baseline and then change the addon to "Drone active zone area is increased by 10%" Her chase potential is horrible and after playing her for 300+ hours I can definitely say that it feels borderline required if you actually want to chase as Skull Merchant.
Secondly, when a Drone is hacked, a new drone cannot be put within 8 meters of the hacked drones physical location until the Claw Trap is removed. This would greatly help 3 genning on its own because it will force the Skull Merchant to either physically guard the gen until the claw trap expires which would allow other Survivors to work on a different gen, or take a chase, which would allow the other Survivors to work on the gen that had a Drone on it.
And lastly, Drones are no longer returned to your inventory immediately after a Claw Trap is removed, instead they now return to your inventory 15 seconds AFTER a Claw Trap is removed. If you take chase with someone with a Claw Trap and down them, this basically won't even affect you since by the time you pick them up and take them to a hook you'll nearly have the Drone back, this only helps combat her 3 genning because now if she decides to wait out a Claw Trap because the previous change, she'll have to wait even longer to get the Drone back.

Why not just increase claw trap battery, that would help her chasing and deny power for 3-gen.
Just cooldown that works even if you down someone seems kinda punishing for wrong reasons.
At least ignore it on downing survivors, you basically pick that drone by hand, no need for it to return.
If battery runs out then sure.
This is a well thought out fix for SM. I just suggested adding a shart mechanic to her power. Your setup is better. Not as funny though.
