I live in San Francisco so freezing isn't an issue. It seems your findings differ from the Leaf forum. They seem to think the lead battery is constantly undercharged so lithium would fair better since the battey's BMS will balance the battery constantly resulting in longer life even at 80% SOC. What I would worry about is the possible 120 amps from the DC/DC converter. Lawrence Rhodes...

The reason the 12v battery doesn't last as long as many would expect is the rather high quiescent loads from the Telematics system. This is the same problem in many EVs today. I think I've discussed why you don't want a lithium battery in place of lead in any vehicle several times here already. (Load dump capability and if you live in colder areas of the country, temps below freezing are an issue.)
