In theory sure, but that sounds a bit too much like a guesstimate that may be somewhat off. Also if the old bushings are trashed your measurements won't be good.
Surely if trashed old bushing or not, won't the angles recorded on the car on the ground still be accurate? And even if measured off the ground, after subframe removal via the outer bushes, won't even trashed inner bushes not under load revert to their correct positions? There is no 100% fixed angle here - the bushes by their very nature have a degree of play so as long as they are tightened at least close to the ideal should it not all be fine?
