No. "Gustarse" would imply that one is pleasing oneself (since gustar is "to please"). I.O.P.s and reflexive pronouns are different.
For example (I.O.P.): esp: Me gusta el libro eng: The book pleases me
For example (R.P.) esp: me ducho eng: I shower myself
R.P.s are used to show that it is done to oneself
