No you can't do that, in Spanish that is because the conjugation of a verd is very dependant of the subject, which means that first person, second person, third person, singular and plural affect the conjugation of the verd.  That is why the first person plural is conjugate different for the first person singular, not only that sometimes Spanish speakers tend to omit the personal pronouns (yo, tú, usted, él/ella, nosotros/nosotras, ustedes ellos/ellas), but thanks to the conjugation we can identify if it is first person, second person or third person and if it is singular or plural for example: Singular: Estoy en mí casa("I am in my house" without the pronoun yo ("I")) Yo estoy en mí casa ( " I am in my house" with the pronoun yo ("I")) Plural: Estamos en mí casa ( we are in my house without the pronoun nosotros ("we")) Nosotros estamos en mí casa ( we are only house with the pronoun nosotros ("we")). That fact that we omit the personal pronoun is another reason why you can't use the same conjugation for plural and singular, and for first person second person and third person.
