One rigger I know use old rigging wire for this, it's easy to push through.
But there is no head cap to remove it might be difficult.
There is another method - never tried my self though..
Place the mast with the side want the new halyard to go down
use a thin line with a magnetic object in the end, it must be small so it can pass through the opening.
Use a strong magnet to pull the magnetic object down i inside the mast.
