Not really.
Virtually every related protocol (e.g. ARP, BOOTP, OSPF, BGP) was modified in non-trivial ways, the rules around different kinds of addresses (link-local, etc) are very different, IP-level encryption stuff started out mandatory (may not be anymore), various flow-control stuff was tweaked (and tweaked again since then to match the improvements in IPv4), rules for parsing optional header fields was tweaked, etc, etc.
- throwaway2048 8y agoAll of those things would needed to be changed for "IPv4 but longer", its not like you could take the IPv4 versions of any of them and use them.
