Any way to fully remove a mannequin from the world, including its script?

[Mud]

Recently, I had the idea to remove the mannequins in a house mod I'm using so that I can use their pedestals to place various NPC "decorations". I tried selecting the mannequins with the console and then using disable and markfordelete. However, I found that this causes two problems. First, the Activate Mannequin option still appears when aiming at the spot they used to fill, and a glance at my save in ReSaver also reveals each mannequin's instance of MannequinActivatorScript continues running, causing a suspended stack for every one. Does anyone know how I can fix this? Or at least get rid of the script issue?
