I would gladly support Inbox, but I can't currently link to a specific thread in Inbox, so clicking a notification would just dump you at the inbox of your email account.
Behind the scenes, it looks to me like Inbox is a new GUI on top of the same Gmail backend, so if the thread linking was fixed this certainly looks possible.
