Um, I think AG3 is pretty much a done deal now. You can discuss it in the AG3 forum, but a lot of work has gone into the new layout and AG3 as a whole. Sorry.
Why do you think sites like Facebook and Kongregate change their layout? Because it'll appeal to a lot of people and only make a few upset, but they probably won't stop using those sites just because of a layout change. Yes, they'll lose a few, but they'll keep the majority.
