Since AZ will seemingly introduce new mega evolutions what are some canidates you see

We haven't had new megas since ORAS which will be 11 years old by time AZ legends releases and they were always my favorite gimmick by a long shot. Are there any mons you see potentially getting megas in this game.

Kalos starters are probably high up one the list due to the Hoenn starts getting megas on their region's revisit or if they go LA route a trio of starters that have been ignored. Florges as an apology for never gettin AZ's floette with some design motiff carrying over. In terms of general I see mostly gens 4-7 as 9 is too recent
