Any IP packet can't be sent if an ARP "handshake" has not been performed. This means that when you are snooping an IP packet you have already snooped an ARP packet slightly before. In which case do we really win something ? On top of that, don't you think that snooping *every* packet will badly affect the performance ? Have you tried measuring the difference ?
