No, I'm afraid not. As we saw, bswift.com is the domain, so this would
lead to an illegal case where you have a CNAME and some other RR.

The normal way to do this is

	       IN    A	  [address of cluster.bswift.com]

There is nothing wrong with multiple A records, but CNAME is processed
differently from all other RRs and doing what you are trying will
simply not work correctly.
