No
Times have changed
You know who else was in the alpha back ground morrigan strider. Capcom just threw folks back there, that doesnt happen anymore. Particularly now where with this street fighter they have began creating an actual fighterpedia and with the last game soft rebooted elements of this franchise. Odds are if they are in the background elements of a stage you are relevant to sf this is how its been since 4. And espically now considering the only elements in the backgrounds of the stages now are final fight stuff , slam masters refences and now rival schools. Two things confirmed connected the first having playable characters and the third being long speculated.
So no, a game in the 90's with an entirely different company ans franchise mindset riding high. Isnt the same as a franchise who with its latest installment actually starting carving out its lore including long speculated members of its world in its world.
So try again i guess
