Not to shoot down your idea, but I don't think the devs would be willing to turn them back on even if a bunch of us offered an extra $10 per month, and that's assuming they haven't been wiped and re-used for AWS already. Having to maintain and monitor (even if only infrequently) the AWA servers splits their attention away from getting AWS up to where it needs to be.
With all of the problems with AWS's stability, missing features, and greater hardware requirements I completely understand the desire to just keep playing in AWA until AWS is more complete. It's what I preferred when they took the AWA servers down, but now that it's all AWS I don't think I'd be happy going back and I know I wouldn't be happy knowing that they have to spend time on AWA when they could be working on AWS instead, even if it's only a little bit of work. And if they did that they'd have to re-transfer all of our gains from AWA back into AWS and make any progress in AWS temporary again which is even more work and time not spent on AWS.
