2700 hours on 320... may I just encourage you to hang in there with your hopes. You might just need to add an SA comm or ATP to those hopes and you should be fine. JAR atp on its own won't work
afaik. Then obviously the whole interview process is next on the cards. I doubt that they'll be legally able to look at you until you get the SA licence. Write the exams, do the flight test in a seneca/etc or hire their sim (the one you're rated on..). You won't be the first to do it this way and not the last. It's also a myth that you'll need to visit a skin cancer booth, so don't let yourself be held up by what others say. Best wishes to you and the others who posted above.
