Answer 1

The simple answer is No.

There is no API for manipulating the image that's generated for the multitasking menu (ie. recently used apps).

Although it's possible to manipulate Back button navigation within an app, when a user presses the Start button on their phone, there is no way to delay or cancel that event.

And when a Navigating event occurs, it doesn't appear to be possible to update the UI or screen in time (the update may happen after the app resumes).
