First of all, the feast day of St. Dismas, the Good Thief, is March 25th, the day our Lord was crucified according the book Saints to Remember (Anne Emmerich also says this if I recall). We know that many of the saints who died justified arose and walked about Jerusalem (St. Matthew, 27th chapter). These were obviously OT saints, a.k.a. possibly St. Dismas. The common opinion is that St. Dismas died in the OT, but I say not so fast. He could have been one of those who heard St. Peter's sermon to the three thousand for all we know. St. Augustine in his Retractions admits to not knowing whether or not the Good Thief was baptized. Why would St. Augustine make this curious remark, opening the door for baptism? I am of the opinion that in between March 25 and the Ascension possibly a great number of OT saints might have been baptized, including St. Joseph.
In heaven I intend to ask St. Dismas, and I am sure he will have plenty of time to answer my question.
