Think you've gone off at a tangent. It was established early on that turn radius will be unaffected to mass.
My point was that AOA would be affected (increased for increase in mass to maintain same g). Of course it would require a comparison of identical airframe types.
High lift devices would also fudge the issue (again like for like comparison required). But then high lift devices usually have the effect of increasing the wing alpha anyway, so probably reinforce the point.
