You know, I was just thinking about this idea yesterday, and then this thread popped up while I was sleeping (yay!). I think this would be an awesome way to mine! What you could do is create a few new fields/re-activate old ones with "Dynamic Mining" while leaving all/some of the current fields as-is.
One place that comes to mind is Omega-2. The current diamond mining field could stay, but one might also create dynamically spawning hunks of uncut diamonds floating around, which could either yield far more Uncut Diamonds, or they could possibly be Uncut Green Diamonds (Apparently, radiation can color a diamond green? At least according to a quick-minute google search), which could be far more valuable than standard Diamonds.
