Doesn't work on Views JS

I've been trying to override Views' ajax_view.js for custom ajax functionality, so this seemed perfect. However, to my surprise, preprocess_views_view() (where Views puts its drupal_add_js() call runs after preprocess_page(), where JS Alter runs its hook. So the hook never sees the Views JS and therefore can't edit them.
I'm thinking there's not much that can be done here, but I do find it odd that it runs in this order -- shouldn't the view process before the page? -- and wondering if you've run into this and possibly found a workaround. (I guess there's always regexing $scripts, or just overriding the functions on the JS side.) Thanks!
