I've thought about this aswell, and was thinking about plopping this idea to Yotta to see what he wanted to do about it.
The only problem is this would be that the Oceans are not big enough, and not linked together to make this effective. The only way this would be useful if WorldEdit was taken into play and made an almost giant ocean linked among the borders of the map right before the outskirts.
And / or if a new map is released sooner or later with the 1.8 features included increasing ocean sizes.
