Pokemon like Pidgey and Taillow are not eligible for Sky Battles but we know in the anime, that they should be very capable in participating in one. If Hawlucha can fly or at least be in air for a considerable amount of time, I don't think that it's too much of a problem for it to participate in a Sky Battle even if it can't in the games.
With that said, I'm excited to see both Hawlucha and Talonflame. Definitely looking forward to their battle and what that'll exactly look like.
