There's probably a lot of room for weight removal from removing interior bits and sound deadening material. Have a look at what some of the driving/racing enthusiasts do to save weight to improve performance...

A good one will be to find the weight of the stock wheels and see how much roof for improvement there is.

Good 16" wheels will be 12lbs or less - average ones weigh 16-17lbs - heavy ones are 20lbs... Hopefully the stock Leaf wheels are light - reducing rotating mass makes a big difference in performance!

The car-seat anchors are probably welded to the body,
and not a part of the rear seats that could be removed.

This could be problematic, especially around the holidays as everyone knows "A waist is a terrible thing to mind."

If the aftermarket responds to this vehicle then I would imagine that you will see carbon fiber hoods, fenders and hatch doors, with hoods being the first offering.

Can't speak about range increase (other than the obvious "lighter = farther"), but rearseatdelete.com makes kits for some cars (apparently not for the LEAF yet, however). For the MINI, they claim you lose 36 pounds. If that little bit helps gas vehicles, then it would definitely help electric. (By the way, the kit is to provide a finished look when there are no seats; of course you can just take 'em out and leave it.)

I was thinking about what kind of urban "cargo/deliver" vehicle you could make out of the leaf if you took out the rear and front passenger seats..... The hood feels pretty light already.

I am personally working on an overall 1% weight reduction. There are 20+ stops and starts on the way to work.

Swap out the glass for polycarbonate.

Recently removed the rear seat "cushion" in our 2015 to put on seat covers. The cushion weighs next to nothing. The rear seat backs do have some weight; you can feel it when you swing them from folded to raised. But I'd guess less than 20 lbs for the whole deal.

Over on evtv.me they have a rule of thumb: Over a long span of time expect 1 watt-hour per mile for every 10 lbs of vehicle weight.
I noticed you're still working with polymers.

Speaking about reducing weight by changing out the glass - http://youtu.be/13B5K_lAabw?t=6m5s
