Replace your wire halyard with a Rooster Zero or Dyneema version.  This specially machined bead has been designed to just take Rooster 2mm zero and if rigged like the image gives a secure lock.  The headboard side of your Zero halyard is your choice - shackle or even a a dogbone.  Steve used this system now for 8 months with no visable wear in the zero around the bead
