The goal of that series is not to reproduce the Mainstream Universe.

But yes, some classic heroes/anti-heroes/vilains could be great: The Punisher, Ronin. A modern Moon Knight ? (maybe one like in Earth-X)

But characters showing up just for the sake of showing up isn't really usefull, so "they could at least have a Tommy Ng appear" doesn't seems relevant (and yes, LW is right, Tommy Ng isn't that much known to be worth an appearance more than others).

But yes, they should expand their universe way more than they do.
