Even if that does happen, for me it still has to come from directly GameFreak. From my logical standpoint, Pokemon Masters is still a product under DeNA, not GameFreak. It has just as much as an approval and support as it does for the anime, the manga, the spinoffs. To me, GameFreak's support of someone else's product isn't enough because of their mindset. I've seen this before and I've seen this type of expansive lore forgotten and ignored several years later through products like Pokemon Rangers, Pokemon Snap etc and these are influential games. In terms of the main series lore, only GameFreak really controls it and thus to me, the reason why I say Blue/Green is the canonical name of the overall character from FRLG and LGPE is that it's the only name of Kanto's female protagonist to actually be confirmed by GameFreak themselves and often with the status quo with fans, such as how the unnamed Rocket Executive from Gen 2 is now referred to as Archer, the Kanto's female protagonist of FRLG is canonically Blue/Green until GameFreak says otherwise.
The second is the separate characters. The real problem why it's so nearly impossible to argue that Blue/Green of the LGPE and FRLG games are separate characters is that there isn't any actual real evidence to suggest this and evidence that people do bring up, like different Pokemon teams or different clothing, more likely suggest that these aren't separate characters, these are different counterparts of a different canon and that's the hard part. How do you convince these people that this isn't a different counterpart? That my logic exclusively suggests that this is a separate character as opposed to a different counterpart? How is this different from Red or Green Oak across the canons? The reason why Kris and Lyra stand out is that the exclusive evidence that suggest that they are separate characters and not simply counterparts is that GameFreak said it themselves.
With that being said, on another note. I can see Leaf as the English name of the anime's take on Blue.
