Inconsistent in what? Balls flying long, or directional?
Pushy technique is often more precise directionally... I guess balls flying long due to the open racquet face? Does she play Conti forhand?
Maybe simple solution is just to switch to slightly more closed forehand grip? It naturally induces more spin, forces slightly mre forward contact point, which in turn opens the stance a bit.
In other words, make a small change and let everything fall in place, rather then deconstructing her technique completely. Then a small change again, later, if required...
