Modification 1

Top of the extension is angled at same pitch as an upper dome strut, making a large steeper flat area that will shed rain and snow better than the flatter round arch shape on the unmodified dome. Transition to the domed areas remove several elements and make a simple integration. A rafter truss type roof is created by attaching horizontal boards.
