[MCU] Could Tony Stark singlehandedly conquer the universe?

Let's say during the events of Infinity War, Tony was able to kill Thanos, suffers a massive mental break, and decides to wield the Stones for himself and conquer the universe.

Couldn't he, theoretically, find the rest of the Stones (Time and Mind) and conquer the universe? Who could stop Ironman equipped with four Infinity Gems?

They wouldn't need to - using four Infinity Stones  would likely be suicide for Tony, just as using six was.  The Iron Man suit and the Infinity Gauntlet seemed to offer some level of resistance to the radiation and the power of the Stones, but even just slotting in one at a time caused obvious pain to Thanos, and we've seen that even just holding a single stone (especially the more volatile ones like the Power or Space stones) can cause serious pain or instant death to humans.  I'd bet that even with the intact Infinity Gauntlet, the power surge of four stones might be too much for a human body to take.

And even if he could handle four, he certainly couldn't handle six.  Tony's death was caused by the power of unleashing the Stones for a pretty small "wish," - don't get me wrong, it was heroic as hell, but it boiled down to "make a few thousand aliens and their ships disappear," while both Thanos and Hulk were able to survive universe-level snaps, things that affected trillions of living things.  The scale of difference between a human body's ability to survive that radiation and that of a Titan or a Hulk is enormous.  The protection of a Gauntlet or a suit only go so far - one big hit of radiation from a big wish or the prolonged effects of constant use would take Tony out long before he could do any major damage.
