I'm not certain. my understanding of how the STS and related magic all works is imperfect at best. If it all switches off completely as soon as the A/P is engaged and the airplane knows it is no longer being flown manually, then yeah, that might help. On the other hand,
AFAIK, the autopilot must have still have some means to trim the stabilizer, so if the erratic AoA is causing the pitch trim problems through those circuits/systems, then engaging the A/P might not make the problem go away.
