Sure. I wouldn't recommend messing with the actual code that generates R.java. Too many potential compatibility problems, etc.
Instead, I'd just use an xslt ant task to generate your helper class -- call it X -- and make it import R. If you like, you can even make it a subclass (and give it inner classes that are subclasses of R's inner classes). So write your XSLT script, call it from an at task in an ant target. XSLT can generate arbitrary text if you use the text output format. In your ant build, just use the target. In your Eclipse build, you'll need to add an Ant builder to invoke your ant task. Under the Refresh tab, you'll want to tell it to refresh the 'gen' directory after your task runs, and under the Build Options tab, you'll want to specify a working set that refers to the 'res' directory and its descendants, so it'll only run when they change. Under the Targets tab, pick your generator target for "Manual Build', 'After a Cleann', and 'Auto Build'. I don't think you'll need 'During a Clean' for this (which would be a different, 'Clean' target) because Eclipse will be cleaning the gen directory for you anyway. That should do it.
