Paint.NET :: Automatic Layers Alignment On Top Of Each Other

Here's what I want to do: I want to automatically align two layers on top of each other.

Let's say I have two pictures. Each picture has a photography in the background and some text in the foreground. I now want to maximize the parts of the picture that aren't blocked by text. The two pictures don't have the same size and additionally, the aspect ratio of both photographies is slightly off. So to align both pictures (e.g. in two layers on top of each other), one of the images would need to be not only rescaled but also stretched (or clinched respectively). Is there a way to do this automatically? The operation itself would be extremely simple:

1. create two "anchor points" (with mandatory diagonal distance to each other) on both images which depict the same part of the picture each
2. run the automatic operation. It justs alignes the anchor points by re-scaling one of the images - nothing more.
