Hi,
Don't get crabby nobody has shaken your hand yet. It's Easter Sunday, lots of people are doing stuff...and to be frank, this topic has been addressed at length in the Aerodynamics section.
You're talking about the many many many things people have already talked about or indeed done in general, and the Template in particular. Check it out:

More than one member has said it before: Your bigger gains are made at the back of the car. They're talking about the vacuum wake and whatever steps might be taken to make it smaller, to make it less intense, etc. It sounds to me like you're looking particularly at the "less intense" part, of reducing the depth of the vacuum behind the car.
Am I reading you rightly so far?
