Place the tiny decoupler on top of your docking port (right side up, no rotation required) and add it to your "jettison LES" action group. Click the decoupler again and move it "into" the docking port (part clipping does not need to be turned on). Place LES on top. Add LES to jettison and abort action groups, then add the decoupler beneath the pod to the abort action group. Fits, works, and looks perfect.
