While this is an interesting idea, it is pretty useless in practice, IMO. Email is by far the app I (and I assume most others) am going to be clicking the most links from, and I'm gonna go out on a limb and say that Apple won't be changing their links to go to chrome. If you use something like the gmail app, they (if they don't already) should probably be doing something like this.
