Is a battery Pit-stop possible?

I appreciate all the enthusiasm and positivity posted thus far. I think however my phrasing of the question was flawed. I don't want to know if it's possible to pit if someone magically comes up with a quick release system, I want to know if it's possible with what's in use today, that is battery (or batteries) held into the chassis often with some complicated maze of velcro (ala the Tekno tray) and wired up to an ESC with one or more plugs, topped off by bodies held in by 3 or 4 body clips.

I'm going to time myself soon and have a real number on the time it takes. Again, it's not a question for a crazy long main 45 mins to 1 hour - because I doubt any electronics can handle running - at race pace - for that long. I just want to be able to finish a 20 min main - with a few warm up laps - with batteries that weigh a reasonable amount.

Pit stops are the real next generation of E-Racing. Running 20-25 mins with two 4s 4500 batteries, with a swap at about 12 mins to keep weight low...that's what I'd like to be able to do.
