How would you draw the Android chrome webview into a UMG image?

We can’t use the webbrowser widget (slate) with Android in 3d space (world), to do so, there is a method, going to the java code of the engine for android and draw the webview into a picture (bitmap) and then pass this image as an array of char to the webbrowser widget class (slate) using the jni bridge.
Does this sounds reasonable? Do you have any other idea to do this or ,how would you draw this native chrome webview that unreal uses as 2d as a texture for the hud?
