Total JS files size more than 1mb - looking for ways to reduce load.

There are currently 17 js files referenced by an Add page using CKeditor, with some scripts inline in files. The total file size is more than 1MB, with yuiAll.js taking more than half of the total size. All of them seems to be minified. I could replace CK editor, but I know that I couldn't remove YUI without breaking the pages even if I try.
Has anyone tried using YUI php loader as an alternative? I could try replacing YUI in the generated pages but it'd probably takes weeks.

please check the "compress javascript files" checkbox before generate your app.

I did. While phprunner already compresses js files, I tried recompressing with YUI compressor but only managed a 1% compression rate.
The other js files are already minified.
I'd like to add that it's not impossible to remove YUI library after the app is generated but it's probably better to remove YUI reference while building the app and using jQuery UI afterwards. I added jQuery validation on the login page on top of the built in validation.
I wish I tried datatables and tableless layout for the list page but now I only have the generated app with me. Another few months before I could sit down and really learn phprunner though.
