g20 suspension

I have an 88 G20 van. I am looking to lower it a few inches. To at least fill in the wheel wells. Sits a little to high for the wife who only 5-2. I am uderstanding g20 is a 2500 suspension. Is it possible to put g10 or 1500 spindles and springs in it? No towing will me with this just a family van. Wife wants a mini van cause g20 is little too big. I don't really want a mini van. I love the room this thing has.

Welcome to AF.
You may get into a big can of bad worms doing things like that.
Lot of safety issues on brakes and suspension there.

I would just get a set of good side steps.
