It won't be a swap.  Even when the local ISP can only deliver IPv6
they will still be able to get IPv4.  There will be business which
just deliver IPv4 to IPv6 only connected customers whether they
need server support or client support or both.  The software to do
this is already written.

Turn on IPv6 native or tunnel.  Populate the IP6.ARPA space with
individual PTR records for the machines.  Add matching AAAA records.
The outbound side should just work.  Next you add AAAA records for
all the services you offer after testing them.
