I think this would be rather difficult on the outbound side as protocols like CIPSO and RIPSO add IP options to the packet. I may be wrong but I thought that adding to the size of the packet was a no-no in netfilter? Also, doesn't netfilter get the packet after the checksum has been calculated and the packet has gone through the xfrm infrastructure?
