Kind of. That's what the old Dream Maps were - the theoretical lowest-priced flights.

For example, I just clicked on the link and filtered a bit to find MCI-SLC R/T for $110 (!). That's gotta be the lowest SLC fare I've ever seen on any airline! But when I click through and start looking around for flights, I never find one under $195 (still an okay SLC fare). I can't even find a calendar that shows what dates the $110 would be available. I'm guessing if I poked around long enough, I might stumble upon $110....or not...

I'm looking for a tool where I say "I want to leave on Thursday Sept 13th at 2PM or later, returning anytime Monday Sept 17, on any of UA, AA, US, AS, or AC. Now show me all of the real numbers on the map."
