I'm not sure that turnbuckle is the right term here. Perhaps you mean a block, turning block or cleat? A picture or two might help.
When I replace a halyard I will use a sail repair sewing kit to sew the new halyard to the old one with a few stitches and then tape over the intersection. Once the new halyard is all the way through the joint can be undone and viola! your new halyard is in place without climbing the mast.
Hope this helps.
