Something that gets me is Levitate–the fact that so many Pokémon whose flavor would lend itself to an interesting ability are stuck with Levitate on purely physiological grounds. Would you consider looking at the Pokémon that have Levitate and coming up with some alternate abilities for them? (The Lake Trio deserve better!) One of my ideas: Gastly (and only Gastly) with a super-annoying ability that makes all physical-contact moves fail. Because how do you punch smoke, really?

Mmm; it is rather overused, isn’t it?  On the other hand, for most of those Pokémon, it would make no sense at all for them to be vulnerable to Ground attacks.  What’s more, Levitate is one of the better abilities out there (immunity to Earthquake, Spikes and Toxic Spikes?  Yes please!).  I think Levitate is probably one of the better arguments for allowing Pokémon to have two of their possible abilities at once.  As it stands, though… well, no, I honestly wouldn’t want to take it away from them!
