Unfortunately, I don't believe any kind of a block of that front opening is a good idea except for perhaps during winter, as the car actively cools the battery during driving and charging from the heat pump radiator up front. While that kind of thing is relatively easy to monitor with an ICE motor, battery temperature is a black hole of information for owners and constant overheating would most definitely shorten the life.
