God-Gale literally is not allowed to otherwise. It's basically the tragedy they build up for him in Origin, he still cares about his friends but he only has one channel left to interact with them - and most of them aren't interest in what he's selling. I don't think, human Gale was in any kind of favour asking position at the time. He does offer to make her a flying axe though, when she says she wants one. I think it's a bit sad we can't really craft one because the exchange is cute. ^^
But considering Karlach is pretty heartless in regards to him, the whole gang is heartless towards Astarion on the docks, the whole can of worms that is Halsin and the brothel ... there are some weird writing choices that make the characters seem crueler than they are supposed to be.
Generally the: "We could have asked X for a miracle suggestions", doesn't sound like a very compelling story to me. The thing that would have made sense to me is all the tiered metals and the lead to talk to the Gondians, that just looked very gamey in the same way that her earlier quest was. It's build up like a lead, especially when you learn more about the factory.
