If you can buy a salvage/used Leaf pack, they can be very economical
compared to Lead Acid (plus, they will give you better performance (more
power to weight) and will last longer than a lead acid pack.
So compare the price to buying 2 or 3 sets of floodies over time....
My Leaf modules only cost me ~1300$ after a LOT of work, but I spent a
lot more on new chargers and a BMS system + the hardware to package them
up into the form factor I needed, + a lot of labor.
Swapping out floodies is a lot less work (but heavier work....) than
changing your entire battery chemistry (and associated electronics), but
I'm glad I did it, as the performance of the truck (speed/acceleration &
range) improved quite a bit, plus the longevity of the pack improved.
(I was getting 2-3 years per pack of lead acid batteries.)

Reading thru the prior comments (which I really appreciate) I am starting to
wonder if I'm getting ahead of the cost curve. Maybe I should carefully
consider if lithium i.e., Leaf packs, is the way to go, at this time?
Another set of floodies is about $3000 and good for four to five years.
Maybe by that time the cost for lithium will be substantially lower.
What is the group thought on this? Pull the trigger ... or wait?
