Edits within a photo on Mac

You may want to try this:

• Export the photo from Photos and save it to folder in the Finder.
• Open the exported photo in Preview.
• Open the same photo in a second Preview window. select the area you want and copy it into the Clipboard, then paste it into the first window with the exported photo and move it to the place you want.

Photos itself cannot combine parts of several images into one image, not even within the same image. Sometimes cloning with the retouch tool will suffice, if we repeat the cloning several times.

But we can copy the main subject of the photo to the clipboard, so we can paste it with Preview to a different part of the image.

I usually use GraphicConverter for stuff like this. But, have you tried using Photos' retouch tool as a stamp? You option-click on the thing you want copied, and then retouch the other thing, and as you swipe, the clicked part is copied there. It's a little funky (you don't see it happen in real time, for instance), but it might do just what you want.

Here I copied the date to another part of the watch face.

Try editing the phone and making the frame smaller. Your question doesn't make any sense but I think I know what you mean. If you have photoshop, or procreate, or any of those sort of apps. You should be able to photoshop it.
