You're gonna need an open mind for this and no i'm not high, but we live in a world of limitless possibilities and for one we're on a floating rock the size of a pebble in the vastness of space. With that imagine if you will that both the DC and marvel universes' actually existed, who besides mxyplyzyk, batmite, and anyone on their level can find a way to our plane of existence. I would ask vice versa from our plane of existence but that's goin to far the deep end.

Are you high???
No, seriously, anyone who can travel between dimensions should be able to do it. Or any scientist who can create a teleporter like Doom, Reed or Pocket verse lex luthor.
Exiles. Anti-Monitor. Monarch. Angstrom Levy (invincible comics, took invincible form Image-verse into 616 marvel). Reed Richards. Dr.Doom. SBP (Eh kinda did when he went back to earth prime..kinda) and alot of people actually. Would it be cool to see in comics? Not at all. Rather boring.
That'd be cool if it were true. Come to world for some r&r away from all the superpowers, demigods, aliens, and whatnot.
As crazy as it sounds i'm not even talking about comics. I'm talking who can actually enter this realm of existence, our reality and i don't even know how they would pull that off in comics.
