If you give up the 7D, you will lose quite a bit of focal length on you Sigma 150-500.
I actually have had that lens about 2 years and only used it once, just to play with it.
I dont really do much wild life.

There are two schools of thought. Having a FF and crop body expands your capacity by adding reach with the crop body and it allows you to select the best option for a given situation. I do this with events, wide lens on the 5D, longer lens on the 40D. Luckily the controls are close enough I can switch back and forth.
The second is have your backup as close to the same setup as your primary so the transition is seamless.
Given that I occasionally need the extra reach and focus improvement of the crop body I keep both.
The reason I have 2 cameras it not really a backup, more as to cover 2 focal ranges at the same time. I can pull up one camera to get a wide angle shot, or the next to get a tighter framing. I use the 70-200 essentially for portraits, and the 7D is not a killer portrait camera as much as the 5D2.
I photograph events, like parties, concerts, festivals, weddings, etc, and I dont really do sports.

If you want the fast focus ability to take pictures of kids playing, I'd stick with the 7D. Why bother with a 5DC when you already have the 5DII? It's just overkill.
I was in a similar situation, and I actually decided to get a smaller, more portable camera to use for my backup- a T1i. It's good enough for everything I need in a backup camera; if I'm taking serious pictures, I'll use my other one.
Essentially, my 7D is my 'throw around' camera. I take it out to chase my daughter around. I dont want a killer lens on it, because, while I trust that the camera should be fine getting bumped, the lens might not fair so well, so I keep a 17-85mm IS on it. I sacrifice some IQ, but retain some cost and ability to not cry if it breaks. I know that I could get a 17-55 f/2.8 IS to fit the 7D, however I do not want that lens, when I already own the 24-70.
I would be happy if the 5D lineup had a popup flash. My memories dont care if a harsh shadow is in the background....
