Anyone who's interested in an idea like this might want to see if Google's Inactive Account Manager is right for them. (Disclaimer: I work for YouTube, which is part of Google.)

It triggers if you don't sign in to a Google Account for X months, where you choose X from 3, 6, 9, 12, 15, or 18.

You can provide up to 10 contacts (email addresses, phone numbers, and custom messages) for people whom you want to be notified once the timer expires. You can also grant them access to the data from your Google Account; they'll need both the link in the email as well as a code from an SMS sent to the phone number you provided for them.

You can also choose whether you want your account to be deleted if the Inactive Account Manager triggers.
