A thick-paint feature to allow a photo to be converted in to a thick paint layer without having to recreate it with strokes beforehand.

When I begin a painting using one of my photos in a layer, I think of it as a highly detailed finished but not dry oil painting.  I want to be able to scrape away with a palette knife and add paint strokes to the "wet" photo painting. That is how I can go beyond the limits of naturalistic and photo-realistic paintings. The feature would essentially change the photo into a thick paint layer of many colors which I could change with brushes and palette knives. Maybe this feature exists, but I am just not aware of it.
