With their plan working, it would have destroyed a great deal of the ecosystem (especially since so many Pokemon live in grass) to make flat, dead areas that could probably still be used by people. Unfortunately, even if it worked, that would create a water shortage for humans too, considering that sunshine doesn't discriminate the water it evaporates and freshwater is fair game. Overall it would make a much larger human society but an overall shittier quality of life, loss of Pokemon habitat, and drought for the larger society, since more development means, ironically enough, that those settlements need more water to sustain themselves.
Without their plan working, well I've outlined the death and damage that would cause.
Aqua on the other hand, is just flat out retarded as well.
If their plan worked, while it would technically be better for water Pokemon like Manaphy and erase some human encroachment, they would end up killing and causing the extinction of most if not all terrestrial Pokemon and a great deal of avians and amphibians.
The actuality of their plan would have ended with the lack of water for Kyogre to draw from, and if it does the fantasy water creation, it ends up simply being defeated by Pokemon healthy enough to defeat it due to the sheer amount of water Pokemon there are. Groudon would have not experienced such opposition because of the deadly environment it creates around it while using its powers without restraint, an environment that not only is optimal for it, but weakens most opponents, save for Pokemon located far outside of where it would have been deployed and used (the ocean).
Both doomed to fail.
