Can "brigade" replace Directx?

Through Brigade, OTOY is now helping leading game developers explore the potential of cloud computing for the delivery of next-generation games. Brigade is a powerful graphics API that can easily replace Microsoft DirectX® or OpenGL® graphics within popular game engines such as Epic Games’ Unreal Engine or Unity, serving as a backend for superior graphics without disrupting the game logic. Harnessing the power of the cloud, Brigade’s sophisticated technology enables real-time ray tracing and path tracing of game environments, simulating light as it appears in the real world to deliver in-game interactive graphics that are on par with the best movie effects of today. Frames that traditionally have taken minutes or longer to render now do so in fractions of a second, allowing for a fluid game experience streamed to consumers’ homes without the need for expensive hardware.

I am thinking can we create a new API like this one and integrate it with UE4 and then deploy games games on PS4, Xbox One , PC etc.? Is this thing possible (hoping GPU vendors and SONY and Microsoft won’t have any problem) ?
