The advanced grapple rope would be current grapple rope with the added ability to "pull" objects. (vehicles, bots, and players.)
The rope mod is a little more tricky. It would be a event that spawns a "rope" projectile between two bricks. on touching this rope, other events can be triggered (traps, elevators, alarms, ect)
Though a rough version of this can be done with onplayertouch, the trigger brick cannot be derendered (This causes a collision problem)
