AWS Route 53 has added vanity DNS in the last few weeks, so you can make your DNS servers appear to be ns0.yourdomain.com rather than ns153.awsdomain.com (or whatever)
However, making your DNS servers to be responsible for serving their own DNS is a bit of an extra complexity and risk that no customer will ever care about..
"You can create generic "white label" name servers such as ns1.example.com and ns2.example.com, use them in your delegation set, and point them to your actual Route 53 name servers."
When you upload a new zone it will be assigned a set of nameservers - four. You can't choose what they are in advance, and you can't specify the TLDs. So you might end up with "ns-1933.awsdns-49.co.uk.", "ns-1109.awsdns-10.org.", or similar.
Does that answer the question? I'm a little hazy on what you're actually asking.
