But for this specific iteration...besides, Miles would just come off redundant with the way they handled MCU Spidey unless they really changed his situation.
If they'd done a better job with him in high school or playing him off the other Avengers it would've been fine in my opinion. And if they'd done more with it than just ape certain Miles Morales aspects.They shouldn't have done it in the first place. We already saw high school Peter twice. Yet the other contemporary Avengers are now in their 30s, 40s & 50s (and with Jan & Hank, even older!). Ideally Miles should've been the high school MCU Spider-Man to begin with
