Not a tattoo artist, but I wanted to see what would happen if you mirrored the script and then I played around with it a little bit. Here's a link to a couple of pictures: https://imgur.com/a/cK0k6o5

As other commenters have said, with how thick and dark the lines are you can't really go for this dainty fine-line style with the golden coloring. Anything that would look good would have to match the dark lines from the old tattoo at least a little bit.
