Do you think that Quentin Beck would have still become Mysterio If Iron Man survived in Endgame?

So the question I have today is that do you think Quentin Beck would have still become Mysterio If Iron Man somehow survived in Endgame.

Now personally, I think he would see it as too risky trying to become this false hero because Tony would probably recognize him and would probably see through all his fake illusions but that's just my opinion.
