I very much doubt it. Change to dual-gauge requires replacing the sleepers, and if they do the very hard work of replacing the sleepers, then why keep broad gauge?
Maybe they would choose to downgrade a single track where there's two, and half of each station's lines, but that would make it very difficult to schedule trains in both directions on a single track. So, they're probably not going to do that either.
