No.

You're mixing interfaces and services. You can have dashes in service names, 
so org.kde.plasma-desktop is perfectly valid:

$ qdbus org.kde.plasma-desktop
/
/App
/KBookmarkManager
/KBookmarkManager/kfilePlaces
/KIO
/KIO/Scheduler
/MainApplication
/kickoff
/kickoff/RecentAppDoc

However, you cannot have dashes in interface names:

$ qdbus org.kde.plasma-desktop /MainApplication
Invalid D-BUS interface name 'org.kde.plasma-desktop.PlasmaApp' found while 
parsing introspection

You cannot construct a QDBusInterface object with that interface name. Even if 
you could, the interface cannot be called because the bus will reject such 
messages. If you try, you'll get disconnected.

That interface name is auto-created by QtDBus itself and should be fixed there.
