"We actually are planning to combine the Fog of War tool into the Dynamic Lighting tool as part of Jumpgate"
This worries me. I don't use dynamic lighting, and I don't see that ever changing. I've experimented with it, and it provides no value to my gameplay and just serves to distract the players from the game itself.
But I use Fog of War extensively.
I don't want to have to configure some kind of "lighting" so fog-of-war can cast "shadows" against it. I don't want to even think about lighting. I don't want a character who's created with blindsight to behave differently from one who doesn't have it.
I just want to say "this page has no dynamic lighting" and "this page supports fog of war" and then make my map (usually from JPEG tiles) and have it work just the way it does today.
If what you meant was "we're going to use the same graphics library to render fog-of-war as we use for dynamic lighting", that's fine. I don't care about the internal implementation (unless you manage to make fog-of-war less performant than the current one; that would be an issue for some of my players with fairly old computers).
But don't compromise the simplicity of the current Fog of War in the process of integrating it with Dynamic Lighting.
