A way to reproject painted details when the model has non uniformly/proportionally changed but has consistent topology or uvs.

Im making assumptions on how some of the projection works but i think most of the projection is dealing with vectors.
What id want is a way to reproject by topology where the topology is the same but the proportions might have changed
It would recalculate the difference in the projected stroke vector by checking against the changes between the old mesh and the new one. Since the topology/vertexorder is the same a deformation field can be calculated off of the vertices that are present through something like inverse distance weighting with which you can then recalculate the new projections.
I`m sure its not as trivial as i make it sound but if anything like this would exist it would be a really powerful tool.
