Not easily or cheaply. The hot-gas seals used in the nozzle gimbals for
the big solids were a considerable technological achievement, and took
quite a while to develop, which is why a bunch of other vectoring methods
were used in the early days of big solids.
A big question though is whether the method would
work for rockets at supersonic speeds.
Since it's been used for ICBMs and orbital launchers for many years, there
is little doubt of that.
