Any interest in custom all aluminum Chrysler steel wheels?

My rear
18x11 aluminum wheel is 29 lbs

Stock
15x5.5" is 21.0 lb
15x7" is 24.2 lb
18x7.5 police charger steel 30.8 lbs.

Not much lighter than the cop wheel. I say this falls into the catagory of “diminished returns.” Does all that money for aluminum really make a difference?
