where did you get such exchange rates?If you are playing FTB Unleashed, you can just go for either an Enderman or Zombie Pigman Tier 5 Soul Shard and get yourself some Minium Stone made.
4 Ender Pearls > 1 Iron Ingot
8 Iron Ingot > 1 Gold Ingot
4(?) Gold Ingot > 1 Diamond
And if I am not mistaken, it works backwards too. 1 Ender Pearl = 4 Obsidian. 1 Obsidian > 4 Wood Blocks(?).

Last time i tried you cant. You can capture them just fine, but when you try to spawn them the spawner just wont start working. Exact mode makes no difference here either.
If you are looking for a iron golem farm, I would suggestthis:
(1300 iron/hour, yes 100% vanilla MC)
I left a tier 5 enderman farm, with an autocrafting center with minium stones, woke up with 200,000 iron
