It costs nothing to try, and if it's a bad idea we can back out. And if it works, then it brings two groups who otherwise wouldn't have any contact with each other together.
My concern is that the representative sent by the colleges to discuss the matter would need to be well versed in both college culture and dwarven culture to make it work, and I can think of just one candidate for that.
Well no, technically it costs an indeterminate but likely large amount of AV to try. For me it's just that the same AV would go to blowing up orcs so it's not like it's wasted.
