600EX-RT on 7D

I have a 7Dand also a 600EX-RT. I am wanting to know that if I buy another 600EX Flash will it work with the radio transmitter on the 7D instead of buying a ST-E3-RT and then another flash later? I am looking for advice and/or suggestions. Thanks

I use (2) 34" shoot-thru white umbrellas. For full length shots the light drops off below the knees.

I would like to know about the light emission characteristics of speedlite 600ex-rt.

What is the intensity of light as a function of time? What is the ignition time? What is the color temperature? Can you recommend some literature on the basics of flash light?
