Considering I've read just as much DC as I have Marvel over the years, yes, I'd like to know I'm aware of who exists in DC.
Also worth noting Reed's not going to be "fighting" these people, but rather just trying to subdue them. And if you don't think someone like Reed, with his tech and prep feats and his scientific intelligence being well above and away pretty much anyone on DC Earth, you're short selling the hell out of him if you don't think a prepped Reed can't wreck shit on DC Earth. And this isn't even saying he wins, but rather acknowledging his capabilities.
Unless you want to dismiss everything he's done as "PIS" or "the other guys jobbing".
Reed's a genius character, arguably the smartest person on Marvel Earth and definitely one of the smartest characters in fiction. You can't just throw out all by 0.1% of his feats because you don't like them.

This is one sided prep.
And while I was joking with my original post.
I believe the task cannot be done even with the stipulations favoring Reed.
The reason why, is because even though Reed is basically a walking plot device, he has also being portrayed uncapable of predicting every single scenario and the amount of variables going on, on taking an earth full of super powered humans can cause Reed to have a misscalculation and IIRC, He has had those in the past.
Civil War actually proved that Reed can and has predicted large amount of variables and multiple scenarios. He even developed a special breed of science for that specific purposes.
I don't think he's perfect by any means, but based on on-panel evidence, Reed can certainly predict behavior on a large scale with multiple variables and possible scenarios.

As a matter of fact I was thinking about civil war to point out this variables that can affect him.
You can see how even though He is such a capable person, he cannot foresee every aspect. This was evident when "Thor" killed Goliath and when He is talking with Jennifer during Daredevil's capture.
The only way Reed could achieve this is if the DC heroes were completely oblivious to what he is doing until he's completed it. this wont be the case. there are several major players who will be aware once he has control of some high level entities. not to mention that the only way to control some will be acquiring. certain talismans like the Ring of Life. He wont acquire that without either Spectre, Fate or Phantom Stranger ( maybe a few others) being aware and without it he can't control them.
