Answered: High poly Low poly - Albedo projection?

Simple scenario:

1. High poly mesh contains UVs with associated normal map and albedo map
2. Retopo to low poly mesh
3. How to get normal map and albedo map from high res to fit retopo (low) mesh?

This is a departure from the conventional workflow - bake high poly down to low poly, then texture. However, it is happening a bit in reverse in this case.
