As far as I know the whitetail programme is a zero-to-hero programme. So if you're going to re-apply for this course, your money would be thrown away. But the experience you get from getting a PPL is very good!
Maybe you can do a glider-course or something like that? Also a very nice experience without spending too much money.
But if you want to spend your money wisely, you can go modular after your PPL and finish your training at the half of the costs from the whitetail programme.
