Can I add a mesh to my r8000p router

depends on how you want it to function. 

you could add a mesh extender to it. I usually only recommend 1 of these. If you're needing more than 1, go with a full mesh system. 

You can add something like orbi to it but you'd want the orbi in AP (access point) mode to prevent a double nat. 

Maybe a better description of what you're trying to do will help us to better help you.
