Well, not impossible, but the only way around this DirectX problem, is to reload everything after a mode change.
But let me tell you - you don't want to change modes in the middle of a game. You might think you do, but actually, you don't. It's just not done. Once you saw it happening, you'd realise how terrible it looked, and you'd take it out again.
