most of those references are video game references, and I am not familiar with all of them(especially these "crossovers"), but video games and comics(especially Sonic) are constantly remaking themselves and throwing canon out the window for playability/new readers, so again a "crossover" that is canon within RWBY going forward with it's plot(which both Sonic and Megaman break theirs consistently) is unlikely. AT could have a RWBY episode, but RWBY having an AT episode breaks the character of the world and disrupts plot.

As I have said, importing another story almost wholesale into your own is not a "crossover", a crossover is when stories mix and affect each other... beyond the "crossover" itself. "Soul Calibur" can use star wars characters because they do not have a real plot/story themselves, they simply built one centered around their characters to explain fights after the fact, and adding star wars characters adds to gameplay.

true "crossovers" are generally made for profit, there is no profit to be made for RWBY to subject it's franchise to another's, and at it's current stage there is likely little profit for another franchise to utilize RWBY.
