Do you think that they could add new mega evolutions or regional forms in the Pokemon Z-A?

mega flygon. I have designed a mega flygon as well as megas for froslass, leavanny, and cinccino (they were for my pokemon fan work), i hope im not missing any there. Its not quite fair that glalie got a mega and froslass didnt while both gardevoir and gallade got megas so thats why i thought froslass should get a mega. Flygon because they never could have come up with a good design and scrapped it so i hope it gets resurrected. Leavanny just because its one of my favorite pokemon, but also you may think “thats random, what would a mega leavanny be like” what if i told you my mega leavanny is bug/steel? Cinccino i think was just random, and its really just a fluffier cinccino. My younger brother thought of megas for gothitelle and reuniclus, but i never got onto designing them. I think a bunch of my favorite pokemon should get megas, i could say all the pokemon in my top 5 favorites (which in that list, gardevoir is the only one who has an actual mega) could maybe get megas, i think the one in my top 5 that probably would most likely get a mega in z-a is goodra, but on second thought, theres a possibility it may not since arceus had hisuian sliggoo & goodra.
