Removing people from a shared album.

Question

My kids have recently started adding non-family members to our collaborative family album. We told them not to do it anymore. But it appears that there is no way to remove these people from the shared album. 
Blocking them apparently will ONLY not show any comments or photos that they add. But they can still see the album contents. And, blocking them not only hides them from the album owner, and still gives them full access to see the album, it also blocks them on Hangouts and other google apps. We kind of still want to communicate with them, we just don't want them in our "family" album since they aren't family. 
Unsharing the album deletes all the comments and the photos that the rest of the family members have contributed to the album, meaning that they would all have to somehow add the photos back to a new album one at a time and they would have to re-comment on every photo all over again to preserve the memories made in the comments. None of these are good options. 
All we really want to do is make the existing link null and create a new link to the album that we can share back to the original, legitimate album members. 
That way we can keep the collaborative album and not lose the photos and comments that have been shared by the legitimate members over the past few years. And we won't have people we don't want in the album having access to the album (whether we can see them there or not). 
This seems like a reasonable request. 
Please help.

@all
This is a user-to-user forum and there is nothing we (also users) can do.  
To request new features you can submit feedback (via main menu in https://photos.google.com/) but I have no idea whether that will have any effect. Many asked for other things (like sort by filename in albums) that were never implemented.

"Is it possible to unshare an album then re-add a limited group?"

To unshare:
Open the album
Select 3-dots > Options
Turn "Share" off. The existing link becomes obsolete.
To share again: 
Turn "Sharing" on again. A new link is created which you can send to who you want.
Edited:   Note that all comments, likes, and photos added by others will be removed. You cannot save the comments and likes, but photos added by others can be saved to your library and added again to the album (as if it were yours).

Removing a person from an album would not prevent him/her from viewing it. Anyone with the link can see. Also "blocking" is not efficient: the user can still view when not signed in. What you need is a completely new option: only specified email addresses can see. Since this is a user-to user forum you better send feedback directly to the team:
Go to photos.google.com.
At the top left, open the Menu , then select Send feedback.

"how do I get someone off & out of my linked album"
You can't. 
others can "leave" the album but you cannot remove them
you cannot remove invitees 
you can turn "Sharing" off, but then no one can use that link anymore
