I think this disrespects those fans to a certain degree. The two characters are clearly different, with distinct origins in their respective films along with the very distinct styles of special effects to show off their super-speed. The characters are not even dressed in a similar way, set in specific cultures and decades based on the plots of their movies. The only confusion I could potentially see would be for overly-excited fanboys who might hope that the character's doubling performances could indicate a coming crossover between the Disney-owned MCU and Fox's Marvel film series. Heck, the movies hardly even call either character 'Quicksilver,' so please, give movie goers more credit that thinking this one thing could be even a bit confusing.
