If I was having my hood remade I'd certainly have the rear side screens removed and replaced by an extended part of the hood as in the picture.
One mod I'm looking at is having a couple of vertical zips put in either side of the rear screen - but easier to get the shopping in and out, can leave it unzipped (and folded back over the hood frame) for more open running, and will make folding it easier - currently it is impossible to fold up without creasing the side windows.
