Nah. To talk to a Dwarven King you first have to be King in your own right. Considering Nazarick's might Dwarves will have nio choice but to grant audience. And as everybody said, given he has taken aura and shalltear with himself, it would be far too suspicious to walk around with an undead as Momon.

Dont forget that Ainz can also offer a lot of unique and rare items from Yggdrasil to the dwarves, and as good as crasftmen and miners they are, i doubt they have better equipment than Nazarick, in fact, its probably impossible. So the way I see it its going to be a mutual trade of some sort.
