Seems that way. I'm not very familiar with bonjour :) Apologies for

It would if you setup WAB directly on that domain, as it seems that
WAB requires PTR records.

The easiest way seems to be just create a subdomain. So if your main
domain is abc.dom, you can have an NS entry on that domain for the
subdomain office.abc.com pointing to your public IP address. After
that, just setup everything (PTR records, etc) inside that subdomain.
Another option would be to just rent a VPS for your secondary nameserver.
