YES this would definitely be great and it’s a thing that I’ve always missed in the game. Either add small zoom buttons or , another idea. Make the large map have a transparecy slider (or make it in addition). I can’t remember the game, think it was Torchlight, but you could set the map to three different sizes, small in the edge, big in the edge or transparent huge in the middle of the screen (and you could switch the map sizes with a button).
I myself often walk around with the large map open when I try to find something, so imagine this picture just without the frames and stuff and only the map itself and it being in a transparent grey-scheme:
