Publish now, email later?

There are several posts asking if it’s possible to publish a post on the site AFTER sending it as a subscriber only email & the answer seems to be no, but is the reverse possible? Can I publish a post to the site now and have that same content delivered to subscribers later? I know this sounds like a bizarre use case, but when writing multi-part series, I would like readers to have the option of reading all parts immediately without flooding the inboxes of subscribers who prefer to get the content one piece at a time.

It seems like it might work to post the content as publish only (no email) then go back and briefly UNPUBLISH the page, then re-publish the same post as publish + email? Would that cause a problem? I’d rather not have duplicate posts, that seems like it would only end up confusing me.
