Yes, I meant adding to the pack myself. After just starting it looks like there are quests for tools that the default iguana config would break (can't make stone tools).
Unless it's been update to make the tools, the quest is only to make the tool parts, not the tools themselves. It reads to make the stone tools, which includes using a stone tool rod this is a terrible idea since that cuts the durability in half.
So adding Iguana TiC shouldn't be too much of an issue.
Suggestion for a recipe for crafting green heart canisters. Because you never have enough hearts.
To get the green heart: Nether Star in shapeless crafting. Simple exchange.
Green heart canister: yellow heart canister + green heart.
