Rather than reinvent the wheel, OpenBSD's excellent PF (Packet Filter) firewall should just be ported and used for Linux and have it replace Iptables. As a former FreeBSD and current Arch Linux user, a firewall similar to PF is an essential item currently lacking in Linux. Otherwise, I support the implementation of Nftables if it's going to be a vast improvement.

Other comments to this article have pointed out that pf has fewer features
than iptables, so porting (really 'reimplementing') it isn't something
that's terribly likely to happen.
