For me, it depends. For example, in the casting for Nightwing, people want someone Romanai to play him since in a few iterations of him, he was Romanai, however the "problem" so to speak is finding a Romanai who looks, and can act like Dick, which isn't easy since there aren't many young Romanai actors.
To me, if you give a good reason as to why the race is different (not being able to find the right actor to fit the specifics, or creating a completely different iteration from canon along with changing name and backstory) then I'll be fine with it. However if they do it just to have a famous name to display, or they just didn't try, then that's a problem for me.
