Coverage wise yes, but it really isn't powerful enough. I guess it could pass with Work Up, but if it doesn't get Nasty Plot or some other boost it gets no higher than UU. While Boomburst is unlikely, Nasty Plot seems very plausible. Even just Hyper Voice would help it out (which it could still get, if some tutor data is just copy/paste from B2/W2 and they haven't changed it yet).
neutral hurricane does more than neutral hypervoice so i'm not really sure how that would help
252 SpA Pidgeot Hyper Voice vs. 4 HP / 252 SpD Eviolite Chansey: 78-93 (12.1 - 14.4%) -- possible 7HKO
252 SpA Pidgeot Hurricane vs. 4 HP / 252 SpD Eviolite Chansey: 94-112 (14.6 - 17.4%) -- possible 6HKO
it also breaks a LOT of walls with its coverage
sorry i know this isn't a competitive discussion, but these new megas don't need to be completely broken to be useful
@ below
252 SpA Pidgeot Hurricane vs. 4 HP / 0 SpD Greninja: 246-289 (86 - 101%) -- 12.5% chance to OHKO
