Actually, it isn't the same thing. Dropping 1 lb. off the weight of a wheel will only improve the MOI if the lb dropped doesn't mean a shift of the rest of the weight towards the edge of the rim.
IOW 1 lb (adding or subtracting) close to the axle is nearly meaningless (i.e. aluminium lugs) but 1 lb at the tread or the edge of the rim is meaningful. And FYI, I purchased some aluminium lugs
I just don't expect any difference in performance

The only real way to significantly reduce rotational inertia is to get smaller (light weigh) wheels. Start talking about smaller wheels around here and all three of us who are really willing to do such a thing will get flamed.
Yesterday, just for the hell of it, I went to find out what size rims are used in drag racing and F1. Looks like drag use 15" or 16" rims as about the largest, and of course the tires themselves are much larger, but when you look at the barrel, it is much smaller than 16". F1 I think works out to just over 14" rims. F1 didn't surprise me, but until I saw the barrel, 16" was a little higher than i expected. When I went shopping for rims, i decided to stay with 18 because of looks. For perf. I was considering 17.
I think rotors like Mike mentioned and the tires themselves are about the only other thing that is going to make much difference past the transmission anyway.

Touché 
but since I am one of the guys who did get smaller wheels, and a lightweight battery I'm used to it. 
In most road racing classes (including F1) the wheel size is dictated by the rules. Usually it is done to limit costs, but in F1 it ended up having the opposite effect. To get the necessary braking power with a small disk / wheel all the teams started using super expensive carbon-carbon brakes.

pair it with 2 piece rotors and you'll really notice it
