Theorymon had a set for this in GenIV at some point, it gets really mixed results. I believe the move set was:
Kyogre@Mystic Water/Sea Incense/Splash Plate
244 Atk/252SpAtk/12 Spe
Mild
Surf
Waterfall
Thunder Wave
Ice Beam/Thunder
It worked last gen because Surf+Waterfall actually KO'd Blissey after SR and Thunder Wave dealt with Latias/Palkia letting your special attacking dragon of choice sweep, but Chansey isn't KO'd after SR by Surf+Waterfall. It doesn't work that well this gen especially because once you do one attack, its obvious you don't have choice specs, Ferrothorn waltzes in and you aren't beating Ferro with this set.
