How do I rebalance the multiblock? 1.12.2 config question.

[Shadow8472]

I want to add Soul Shards to supplement a mostly "vanilla with toys" modpack, but the multiblock is too cheap for our intended use in endgame gameplay.

We want the following substitutions for the multiblock:
Diamond -> Nether_Star
Quartz_Block -> Purpur_Block
Obsidian -> Endurium_Block (ThermalFoundation:Resource_block 7 or something)
Glowstone -> Lumium_Block (ThermalFoundation:Resource_block 5)

The pre-flattening block states are tripping us up here. We've figured out the others. I know this would be better suited to a JSON forum, but I don't know of one. Thanks.
