No, I think you can't "start it up" only "when needed".
Replication would be compromised, the backlog window is about a week

But what you could do is to keep the first master reachable only by
other replicas through firewalling/vpn/vlans your choice.
And expose to the real world only the replicas.

In this scenario you can shut it down without much care because it is
not serving clients. But you cannot keep it shut for long times or it
will get completely out of sync with the other replicas.

Of course, as Rob already pointed out, you may want to add replication
channels between replicas so that your master server is not critical
for replication if you have to shut it down.
