New 2 stroke design

I was sitting working on my Goped and I remembered turbo charging 2 strokes. And how it doesn't work because the both the intake and exhaust valves are open at the same time. (that and there isn't enough exhaust pressure IIRC) This is also the reason 2 strokes waste a lot of fuel through the exhaust port. So my question is, could you just re-engineer the two stroke with only and exhaust valve? Then you could have it close at the engine of the exhaust stroke and then have the supercharger push in air. I think it would have to be supercharged and have a heavier fly wheel, due to the nature of two strokes. I am having a hard time getting a grasp on what i'm trying to say, so if any of you could tell me if this is/isn't possible that would be great. Does doing this defeat the purpose of a two stroke?

This is sort of the same thing, but it does not require a supercharger.
