I'm certainly no expert, but...
Besides the cost and additional hassle of pulling the stick - I see little benefit in re-engineering your mast terminals.
I've just replace all of my standing rigging (myself) and terminated each with either StaLoc or Norseman mechanical (re-usable) terminals - purchased all online at tremendous savings.
Norseman makes standard T-Ball fittings & Rounded T-Ball fittings (aka Lolipops) and are matched to a number stamped on the corresponding mast socket.
All can be made quickly & easily (even at sea) with nothing more than two adjustable wrenches, a hacksaw and a dab of sealant
. I've been using (and installing) mechanical terminals exclusively since 1994 and have never had one fail in 25,000 miles across three oceans.
Best to stay with what you have.
