Sullpond, I like the idea for a DIY project, and yes it should help aerate. However, (and I hate to sound like a broken record) water (8.34 lbs/gal)is a lot heavier than air. It is much more energy efficient and therefore less expensive to move water by way of pumping air. It is also a lot less expensive to run PVC air conduit from where your electricity currently is rather than running copper wire.
P.S. If your looking for an excuse to spend some money, give me a call. You can give it to my wife to go shopping with so that she'll let me go fishing this weekend. Talk about money well spent.
