I think Shauna went to live with her Aunt if I'm not mistaken?
I would go have and bring on Johnny, Connor, Lucy as teens too. And perhaps another teenage girl unrelated to the canvas to form a teen scene. However, probably due to obvious lack of budget and COVID it probably won't happen. Maybe, Kyle, Jack, Summer and CO. can rebrand Glo By Jabot 20 years later bringing them together.
Johnny can be the "Golden Boy" of both the Newman and Abbott families causing a rivalry with Connor who is the black sheep. Perhaps, Chelsea decides to finally bond with Johnny the son she gave up which can cause drama between she, Billy, and Victoria. Johnny and Connor can also rival over for Lucy's affections.
Chelsea decides to tell Johnny the truth about her being his natural mother but Victoria threatens her not to do so. Connor overhears them two arguing and decides to rub salt in the wound at his brother/cousin revealing it at Johnny's Sweet 16 Birthday Party i.e. Phillip on Guiding Light finding out about him being a Marler.
So much potential with having a teen scene again. I just hope the writers don't screw it up like regimes have been doing for years now.
