If you're changing the templates, you may as well organise them a bit better. What I mean is the current layout of the pages is quite horrible. Imo there should be a package list on the front page, since that's what people are coming for, and there should be a login box on every page. It may be hard to do with the code base but if you're seperating business logic from presentation then it would be much easier for changes like this.
Of course you can always wait (or help with) AUR2 :P
