i saw a show once where they notched the body down over the frame to give the visual effect of the truck being lower ?? you would have to do more research about it and have the guys on here give their opinion but why not ?
That technique is called "Channelling". Been around for many many years. Generally, it's done on '20s-'mid '30s vehicles were the frame rails are close to outsides of the body. It involves cutting out the floor pan, then raising it the desired amount. It does reduce headroom.
