Possibility to integrate UE3 into visualiation tool?

What I need is to test a visual simulation tool (automatic mesh rendering for auto-assets creation).
What I currently use is semi-rendering tool (self-developed) using DX11.

I have 2 questions:

  1. Is it possible to replace my rendering piece of code with UE4 rendering so to visualize those meshes in my tool. (At later stage plan to use UE4 for the game itself).
  2. Is it possible UE4 to be used in Modern UI (Win8) app. Does it support DX11.1 /11.2, if not - any plans?

Thanks in advance for any competent response!

Pls read UE3 as UE4 :wink:
