It works with Weakness Policy at least. Switch into Aqua Jet for +2 on Attack and Special Attack and +3 in Speed (it says "drastically" in the website screenshot). It's still situational at best, I guess.
At this point it's theorymon, but if the powercreep isnt going drastically down, you are not safely switching into Aqua Jet in a real scenario. You have to take 2 of those Aqua Jets, which in OU come in the form of CB or BD. It won't be switching into Hydropump or Rain Boosted Scalds/Surfs. It's similar to Palossand's in the sense that you gave it the ability to boost be receiving the most lethal attack type it can afford to. If the ability activated after Ground Type attack it would be better.
I know you're memeing, but depending on the stats and potential evolutions of that pokemon, Passho berry could be a viable option, allowing to flat out eat a water attack and then outspeed the turn after.
It needs not only the Speed Boost but the Attack boost too. If not, you could see already lots of high attack rock polish rock type Pokémon fulfillng the same role.
