Generative Blend Brush

I would love to see a tool like the Generative Remove Tool that is specifically tailored to blending two layers or part sof an image together. So for example, I want to copy a garage door in a real estate exterior photo and use it to "close the door" on the other side, I could copy and paste the door, then use the Generative Blend Brush to go aorund the edges and seamlessly blend it all together. You can already sort of use the remove tool and Gnerative Fill this way, but it would work great as a brush developed with this in mind.
