"Let's cook the sweet potato."
Translation:E hoʻomoʻa kākou i ka ʻuala.
Based on what you said about verbs and pronouns, I do not think it is right. Stative verbs as well as other verbs can be used with nouns, pronouns, and proper nouns. Just to clarify one thing as well, hoʻomoʻa is not a stative verb. The word moʻa is stative, but hoʻomoʻa is transitive because of the causative prefix hoʻo- .
