how about merging different gmail accounts?

…a real good goal for an efficient management of many personal gmail accounts: wouldn’t it be great if we can merge them under a unique google profile and control them in a proper tab in google plus?

this is my case

I have several accounts, opened for specific circumstances: one for personal mail, one for social networks and other services, one is a replica for my business calendar (my company’s office suite is not configured to be used via mobile – sob – so I had to work it out, and gmail was the solution of course).
At the moment, it’s possible to configure “multiple account options” in our gmail account, but it only works as an account switcher.
What I need is that Google recognize me always as Marco Frattola’s profile, with differents mail/calendar/docs account. I’ll be satisfied if only emails were distinct.
