A few, very fortunate people might be lucky enough to find salvage 40 kWh packs for around $10k - $12k USD, as well as a heavily degraded, yet otherwise in good condition, older LEAF for under $5k - $7k USD.
Given what used 2018 LEAFs are selling for in this insane used car market, less than $20k all in (car + pack + CANBUS bridge + installation) for a good condition LEAF with a healthy, 40 kWh pack is a comparatively good deal.
I personally wouldn't do it even at that price though, as the current car market is way overpriced.
