Using AI for fake historical portraits
Hi I'm creating an ARG right now and I've found myself in an ethical dilemma or maybe I'm just not thinking outside the box enough so I've come here for some advice. I'm making it to add lore to my comic book I've written and illustrated. My ARG has a lot of pieces from WW2 and for that I need real historical photos for the 2 characters I've created. They both have very distinct looks. Its hard finding historical photos of people who resemble these characters especially since one has a very prominent mustache that really wouldn't exist on a U.S. Army general at the time due to uniform code. I've floated the idea of using real people and photoshopping the mustache on them but it just doesn't look the way I need it to. I'm considering using AI for just the historical portraits but I know it's the last step to calling my project creatively bankrupt. My project has so much hard work built into it and I don't want people to see this one thing and call it slop. Any ideas on how I can get around this or would you consider a couple set pieces ethical?
Edit: I just thought of the fact that using real historical people and altering them to play a fictional character is essentially stealing their identity and likness which is a whole other ethical dilemma
