Same logic as Marvel's Unstoppable Wasp. Nadia was announced as Nadia Pym. But in the final issue, having just overheard people talking about the fact that Hank Pym (who she believes is dead - he's really merged with the villain Ultron) once hit his second wife, Janet van Dyne, she decides to take her step-mother's surname instead of his.
Yllaw? Kinda weird that Where's Waldo's Odlaw isn't called that in the UK, since it's called Where's Wally here.
Waid's something else was also Marvel, wasn't it? His first Captain America run? He's currently working for both Marvel and Archie.
Actually, Miles IS starring in the next Spider-Man movie, it's out next year. It's a cartoon, though, so distinct from the MCU series starring Tom Holland as Peter Parker. Homecoming did have a deleted scene where Aaron Davis mentions someone called Miles (his nephew, in the comics).
At this point I think it would be weird for Wally II to get a name change just to make it easier for people to differentiate.
I imagine people might start calling him Kid Wally and just have it grate on the character when people do that.

i think they can just keep it the same
If you have to resort to calling him a nickname or a shortened version of his name to differentiate him then I think just giving him a new name would work better. It seems like a much more streamlined solution than trying to find ways to work around calling him Wally.
Why would it be weird? Lets say they decide to create a new Robin character that is black and his name is Richard Grayson too, or a new Wonder Girl character who is black and call her Donna Troy, while keeping the main Grayson and Donna characters around. That would be weird. If you basically do what they did with Wally to any other character that is what is bizarre. People would be scratching their heads.
