This seems like the right place. ;)
First and foremost, figure out if your Roll20 group is down with Fate Core. If not DFRPG isn't too much more complicated. It has a few tweaks that represents Dresden's Universe Well. The whole free will thing comes to mind.
I know one of them doesn't like Fate Core itself, calling it a skeleton of a system. He likes meat on his games. Two are really into Fate Core, but haven't gotten much chance to actually be involved in FATE/Fate games at all. The others all seem either ambivalent because of our last three Fate Core games or happy with anything as long as a game happens with little setup time.
The first guy is why I'm considering Dresden Files RPG itself, and the last one is why I'm considering Fate Core. DF takes a /lot/ of prep time. Last time I tried it, we did three sessions of setup: City creation, Faces creation, and Character creation. It was nuts and put everyone on edge. I'm not looking forward to that part again.

If you drop Powers, vanilla mortals are going to be dropkicking a whole lot more ass than in the Dresdenverse. In the books it's hammered again and again that vanilla mortals are out of their depth when it comes to dealing with Supernatural Entities. DFRPG does an excellent job of representing that power curve between "monsters" and mortals while also given mortals extra fate points to have more narrative control to account for the discrepancy in power. Putting everyone on equal footing means that mortals are going to be a lot more powerful.
Dropping Powers wouldn't put supernatural creatures and mortals on the same footing. Supernatural beasties of the NPC variety would have inherent Weapon and Armor ratings of their own, absurd skill levels, and very specific opportunities to invoke and compel aspects. PC supernatural creatures would need to list out what kinds of things their aspects can do for them (being a Vampire, I can invoke my high concept for superspeed, superstrength, and super toughness, but compel it when I need to feed or run across a weakness). Also they'd have Stunts at their disposal that mortals wouldn't have access to, like the aforementioned Weapon and Armor ratings, weird abilities that otherwise modify skills, etc.
Or I could just take a harder look at Atomic Robo and have people use Megastunts in place of Powers, by which I mean not actually dump Powers at all. I think Megastunts might work better than the Powers from DFRPG, as I recall being nickel-and-dimed to death when making my own DF characters and helping my previous players. Except the Wizard, who basically won at character creation. Not really what I want.

Weapons and Armor will be super easy. Values are all listed in DFRPG already.
That's true, and they suit the setting exactly. I'll need to take another look to see how the DFRPG and Fate Core ladders compare. I vaguely recall DFRPG's numbers being generally larger than Core's. Still, a fantastic place to start.

It could work well as long as you keep a grip on the Fate Point flow. If Fate points are precious, then this is actually a compelling consideration. Do I go big and risk failure, or do I play it safe? I'd fail at running a system like this. I give out a lot of Fate points.
Heh. I tend to stick to Invokes and Compels for the FP economy, rather than passing them out like Savage Worlds bennies. My games are just more rigid and structured.
