I believe this is being over-though. Lithium biased batteries have a max. discharge and charge rate, in amps. Exceeding either will damage or destroy them. Its your money, you seem to have a grasp on realty. Make your choice biased on you knowledge.
Grover, I believe you're on the right track if your new batteries have a built in charge controller. As far as alternators not being able to fully charge house batteries, that's non-ยข. A steady charge at 14 volts for a full day of driving will fully charge lead/acid house batteries. If you are concerned about over heating you alternator with Li batteries, why not put a temperature sensor on the alternator before and after the battery change and see what happens. I see so much hype about burning out alternators but no solid evidence.
