This isn't really a powerDNS question, but I'll answer briefly anyway.

The glue records for NS1/2.MOMO.COM are irrelevant here.  When you move 
momo.com to route53, you'll be assigned a new set of nameservers, e.g.

momo.com.    43200    IN    NS    ns-1143.awsdns-14.org.
momo.com.    43200    IN    NS    ns-1944.awsdns-51.co.uk.
momo.com.    43200    IN    NS    ns-422.awsdns-52.com.
momo.com.    43200    IN    NS    ns-964.awsdns-56.net.

Therefore, you change the set of nameservers to that list in the 
registrar.  ns1/2.momo.com are not used to serve momo.com any more, and 
hence the glue records are no longer required.

Equally, this doesn't affect any other domains which are remaining on 
ns1/2.momo.com, since ns1/2.momo.com will still resolve to your 
nameserver IP addresses.

When you move those other domains to route53, you'll have to change 
*their* list of nameservers too (and note: you may get a *different* set 
of nameservers for each domain you move to route53)

When you've finished the whole process, you can decommission 
ns1/ns2.momo.com

Regards,

Brian.

P.S. the domain "momo.com" is currently running on nameservers 
"dante.enter.it" and "dexter.enter.it"
