That would imply to let the drivers parse all headers to figure out the length. I think it's better to have a "header base" and "data base" pointer. The driver would just copy some standard size that likely contains all of the header When you're finished with the header use skb->database+(skb->hdrptr-skb->hdrbase) to get the start of data.
Or did I misunderstand you?
