Had you considered a SS 'chock' welded on and bridging the entryway for the halyard? I admit this could add leverage of a twisted halyard to bend the entire assembly causing more serious problems...
I don't think it is possible for the halyard to get hung up on the edge of the sheeve (where there is only approx. 1/16" of clearance on each side) or on the top because it is rounded and sloping down so I can't really see a need to do what you are suggesting (if I understand correctly). Of course only time will tell for sure when she is getting used.
