How to reduce the weight of laptop power adapters ?

Laptop Power Supplies

Is it possible to replace the transformer/inductor in a off-line type flyback converter by thick power-cable of equivalent inductance? In other words how can we reduce the weight/size of the laptop adaptor circuit which is majorly big/heavy due to transformers and other reactive components.

Thanks..

I don't really see how replacing "normal" inductors with thick power cables is going to make anything *smaller*.
