I’ve been thinking about this too. I think that it may well be worth it.

Home made batteries probably always be larger in size to provide the same amount of power as a factory battery, but there are some serious advantages too.

If a single cell in your DIY battery goes bad, you can just replace or repair that one cell (instead of the whole battery).

If a plate goes bad, gets sulfated, or gets shorted by settling metal flakes… I think that it might be realistic to just remove all of the lead from that cell, melt it down, re-cast it, and just put it right back in (does anyone know what happens when you melt lead sulfate?)

If it turns out that you can melt lead sulfate to recycle the lead… then your number 1 source of scrap lead would be old dead lead-acid batteries.
