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.
To Life!
