Good idea but I'm not sure how much that sort of thing will help to prepare you with getting through the course at Hurn. There's quite a few specific things that happen at the college that don't really happen in the 'real' world - although you'll get some good experience, you may pick up bad habits at the same time.
Work experience at towers would have the same training help/hinderance combo. If anything, I'd say knowing how to fly and the related theory seems to help the most with the theory side of the course - although that's not going pay you!
Good luck - PM if you want to know more about college.
