I think this subject is being completely over-thought.
If your hooks are razor sharp and your rig can reset you're worrying about nothing imo buddy. You have to bear in mind that the tighter you fix that lead, the easier it is for carp to use that lead to throw the hook.
If it's that weedy just fish bowstring tight lines. The lines will be hidden in the weed and a single beep equals a bite. Dead easy mate.
There are numerous inline set-ups available, and heli set ups, and lead clips, and they all work as intended out of the packet. You don't need to be butchering them unless you're looking to create something really far-out or completely unique. Jamming the lead on is just not the one mate.
If you truly believe that this issue is costing you fish then you need to be thinking about the feeding situation imo. If they are feeding that gingerly that the lead systems that work for everyone else are not working for you then there is something fundamentally wrong with feeding situation.
If it were me I'd be chucking a lead clip out there with a very sharp hook knowing full well it'll empty the place if put in the right spot.
