I don't think so. Additive multiple inheritance if this is what you mean is
not there.
The main application of additive MI is rather intentional duplication of
operations and components. E.g.
type List_Element is tagged record
Previous : not null access List_Element'Class;
Next : not null access List_Element'Class;
end record;
type Alarm_Event is new List_Element or List_Element with record
...
end record;
Inherits twice from the same list head in order to be able to participate
in two lists: of alarms and of events.
This would require operation and components renaming.
