Conditional statement to force two raster elevation surfaces to not intersect

Using ArcGIS Pro, I have 2 raster elevation surfaces over a large area I will call Upper and Lower which should never intersect. The Upper should always be above the Lower surface. The elevation difference varies between the two surfaces. But because of errors or inconsistency in the data occasionally they intersect and for instance over a small area the Lower may rise above the upper. I am looking at creating a conditional statement where if the Lower>Upper it takes the average elevation distance between the two surfaces in the local area (beyond the erroneous intersection) between the two surface and pushes down the lower surface by that amount so the two surfaces no longer intersect and in the area of the erroneous intersection and the Lower is now below the Upper by the average elevation difference between them in the local area.
