Add two layouts to a leaf

Hello community, 

I am wondering if it is possible to add two layouts to a leaf. The scenario is as following: 
I want to create an organigram to show the hierarchical structures of a company. But at the same time, I want to display the employee's roles. It should look like this:

                                   J. Doe
                                       |
            --------------------------------------
            |                                                        |
      M. Schmitt                                A. Lee  --- Program Manager
                                                                     |             |--  SAP Expert
                                                                     |
                                                                     |-- J. T. Kirk --- Project Manager
                                                                     |
                                                                     |-- M. Spock --- Scientist

So, the main map is structured as an organigram, but for each leaf (like A. Lee), it should be possible to add to the right side his roles.

Do you have any idea how to realize this?

Thanks and best regards,
