I did see that Victron video a long time ago about hooking an LFP up to a stock alternator before, don't remember all the details of it, but the basic jist.
Is it the Balmar alternator you were looking at, which is the solution? (with temp sensor and can reduce field current to allow not to overheat)

Recently we heard how Stefanie fitted Lithium batteries and renewed the electrical system on board her yacht Taku Moe. She soon found that her old alternator wasn’t packing a big enough punch for her new batteries – and wasn’t surprised. Here she tells us her experience of installing a...

I guess they seem a bit spendy, is that the issue, we're looking for a cheaper solution I'm assuming?
Could 2 smaller 24v input, isolated 12v chargers be used to charge each half of the LFP bank separately?
Or these Victron Orion chargers are isolated, and says you can parallel them up for more amps...
Could either do 24|24-17 on the whole bank with multiple paralleled, or perhaps multiple 24|12-30 with half on one 12v and half on other 12v in the 24v LFP bank.
Just thinking out loud here...
