This is pretty valid, but its honestly pretty easy modular math? And I don't think we'd ever consider liquid iron in terms of 'bottles' since that's (as far
as I have seen in existing mods) just a thing that's not done. Would be, assuming 3 bottles a bucket, 'One bucket/block, 6 ingots, and 3 nuggets of
liquid iron'. TiC for 1.12 had a thing that handled it pretty nicely, and the UI side of things is mostly mod controlled right?
