You may have a different idea of what "refreshing" means than I do but I dunno if you could do much to this kit to make that word apply. This is a pretty big beer for a kit.
What are you after from the hop additions? A 30 min addition will add some bitterness and a fair whack of flavour. The 5 min would add mostly aroma. Your plan sounds alright to me - having said that I think the time I did this kit I did 35g Fuggles @ 60, 35g Fuggles @ 15 and 20g Fuggles @5 and if I were to do it again I'd up every addition, but I can see why that might not be for everyone.
[EDIT: I'd seriously consider using malt on this one if I were you. Maybe cut it with a small amount of dex if you want, save the BE2 for a more subtle kit].
