Something I've been thinking about a lot in terms of the Golden Age is the fact that the Invaders just... aren't real. That's a fake concept writers retroactively made up. Other than Jim and Namor, none of those people knew or talked to each other. Like, I've read a fair portion of Marvel Comics, Captain America Comics and I've also begun reading All-Winners Squad and of the Golden Age Marvel stuff I've read, there are exactly two moments where something that could be considered Invaders-lite happen, and both of them are in text stories, not in the main comic.
In this one, it actually ends up being a dream that a little boy is happening, so it isn't even canon.
The other time is much closer to an actual canon event, but Captain America isn't there, and it seems like Aarkus is the closest thing to a leader of the group? Which is interesting.
Other than that, these people did not interact with each other. Their stories were entirely self contained. Other than Namor and Jim, those people did not talk to each other. And it's possible they will later and I'll look like an idiot but at the moment, the Invaders are more or less a concept that people made up to compete with DC's more established JSA, which actually did directly talk to each other from time to time.
