Everything should work fine. From your descriptions I am assuming everything is '06 or older? The front should be friction so that shouldn't be an issue and while they did shave a little on the width in the front it isn't enough to stop things from working.
I do have to admit though that when i had it set up on a 10s triple I didn't like. Your extra cog is probably going to be around the 18t cog and most riders really don't notice it. And campy really only has one triple ratio of 30/42/52
Do you really need the top that the triple provides? Have you thought about a super compact double, say a 30/46 with the 10s rear?
