Sort of like how Mawile and Absol were affected. Hell, gen 3 alone has Cacturne, Gardevoir, Sharpedo, Crawdaunt, Camerupt, Manectric, Sableye, Zangoose, Seviper, and the two sun/moon themed rocks that could probably make use of mega forms.
As long as it doesn't get in the way of ensuring we get the 100+ new Pokemon each gen brings to the table.
