I already figured the sketch thing was possible even if you couldn't program new abilities in. All Sketch moves would be listed as 'Breeding' and you couldn't chose more than one per set without them being illegal. That said...
Boosting Hail just for the sake of it won't help much imo. Abomasnow still has to be the one to set it up and the other weather starters have a lot of advantages over him in OU. Even Kyurem couldn't change Hail's obscurity this gen. On the other hand, I'm about as excited as Rising Dusk to see what we can do with Sketch Artist, to the point of having jot down some ideas already.
