I like hexes too, but I don't need to agree with the OP's premise to give constructive feedback. This argument seems like a non-issue.
Instead of dropping Fool, you could just change the boons to vanilla bonuses. e.g. receive 3 boons -> +3 cards, and Lost in the Woods lets you discard a card to draw a card. I think that would be a pretty reasonable card. I wouldn't pair it with lucky coin though, that's just asking for big money games.
I don't really think Cobbler needs a buff, and adding +Action is probably very strong. I'd be worried that if it's too strong then it 3-piles too fast.
Giving +Buy to Raider sounds fine. I don't really like Raider that much even when it's good though.
I'd pair Leprechaun with Poverty or Envy, preserving the phenomenon where you're afraid to play Leprechaun if you're not getting a wish because it might ruin your turn.
I'd pair Cursed Village with Misery or Envy. Misery only really hurts if you're the only player getting Cursed Village. Envy probably doesn't hurt at all in the kind of deck that likes Cursed Village, but sometimes it might. Or maybe just forget hexes and take your -1 coin token.
I'd predict that your take on Tormentor is very centralizing. I mean, junkers often are, because you don't want to be the only player gaining them. But you know, if a card makes you jump through hoops to junk your opponent, often what that means is you're just going to spend more of the game jumping through hoops. And it's not like Idol, because you often don't want silver in your deck, but imps are good in almost any deck. But it might be fine even if it's centralizing--Imps are interactive. I'd test it to see if it has a runaway winner problem.
