lacerate is a bit of a tricky skill to go elemental with. you need to be hitting bleeding targets to get a good amount of damage on it, so you can't go full elemental conversion.
the way that's probably the best to do an elemental lacerate build is to go queen of the forest and dreamfeather and use added cold/ice bite for your main sources of damage. that way you keep a bit of physical to still apply bleed. dreamfeather deals quite a lot of damage, especially if you get a good evasion from going raider and get some flat elemental abyss jewels.
if you want to go more of a conversion type elemental build, you can use either physical to lightning + the 40% to cold on the tree or hrimsorrow with the 40% to cold on the tree. either of those puts your damage at 90% elemental leaving 10% to apply bleeds. the size of the bleed doesn't matter at all, it just matters that you should be hitting a bleeding enemy. that lets you also add in hatred which is a good damage boost as well.
i hope that helps.
