I don't think anyone is going to be able to say with confidence whether it's going to make a difference or not on your particular car, with your current wheel covers as a starting point. (Unless they tried it on a car like yours, with those wheel covers.)

Why not try it out yourself? Cut out 4 cardboard discs, grab the duct tape and do some ABA coastdown tests / terminal velocity downhill runs to see if you can detect a difference?
