Before I begin, I want to compliment you on your English.
I think you are overreading the intent of the five basic sentence patterns. None of the basic five have modifiers listed. That is most likely a leftover from diagraming sentences. In that scheme, modifiers were depicted below the main sentence line.
Certainly S-V-adverbial is not an uncommon sentence pattern;
nor is S-V-O-adverbial. These are both covered under S-V and S-V-O.
