Really, really, really unlikely. For starters, you are talking about two cameras, which presumably are going to be attached to the USB ports, and then a wifi adapter as well on the same bus (since the Pi 3's built in is 150 Mbps); in theory it should allow for this, but in reality I've never seen anyone claim that it gets much beyond 50 MB/s all told, and that's doing one thing via a USB cable.
The best chance you might have is using a Pi 3 with a second USB wifi adapter (on a different wifi channel or frequency, which may make things awkward), and a Pi camera on the CSI port, then a USB cam, to share the load around. At best I'd call that an interesting demo/experiment and not something that should be recommended to people who are shopping around with a specific goal in mind.
I believe there are add on boards that will allow you to run two pi cameras on the CSI port but I do not know how well they actually perform; again you are looking at very bleeding edge as opposed to proven technology.
