This might help a little.
You can have it remove notifications and create it's own notification count. Like soaking in them all to itself.
It is not 100% what you are asking for but really close.
Try Notifly: https://play.google.com/store/apps/details?id=com.flyperinc.notifly&hl=en
Been using this for around 2 years and their free version includes everything I need. Might not work for all apps though.
Could you share the project? The app I mentioned in the post, doesn't work "when a bubble disappears, the notification also disappears" and "when notification disappears , bubble disappears" function properly. Now I'm fix this manually using tasker. But I thought it would be awesome to make the task working the app similarly.
Notify should allow you to do the chatheads thing with WhatsApp, Telegram, GroupMe, Hangouts, etc. I haven't tried it myself, but it has a 4.1/5 star rating.
Sry to tell you, but this already exists for more then just WhatsApp.

notifly works with textra/messenger/other SMS apps. https://play.google.com/store/apps/details?id=com.flyperinc.notifly&hl=en
Not really a messenger app, but Notifly uses notifications to make a sort of floating client for any messaging service..
Notifly might do the trick for you!
Personal favourite of mine would be Notifly. Their trio of apps are all pretty neat tbh. https://play.google.com/store/apps/details?id=com.flyperinc.notifly

How does it compare to Notifly?
I use Notify. It works even better than quick reply. Battery life was so bad I hab to go back to M
