Changing the checkpoint time won't have serious effects on ctl_deliver's
time to run, only ctl_cyrusdb -r's

How often are you running your ctl_deliver process (with what sort of
expiration time) and how many messages do you see in a day?

You can't do it while the server is up.

It will cause duplicate messages to be delivered (once), and vacation
messages to be sent again.
