Each of the synoptic writers did a masterful job of taking his source material and shaping a coherent narrative and thematic consistency. So the unity of Mt 28 doesn't prove Matthean priority anymore than the unity of Mk 1 and 2 would prove Markan priority. Their relationship has to be decided on other grounds.

...the final verses of the Gospel of Matthew...are in fact the perfect ending for the Gospel of Matthew itself, with numerous tie-ins with themes and concepts developed throughout his own Gospel. Without the hypothesis of Markan priority (and it is an hypothesis, which means that Matthew cannot rightly be described as a "known" reader of Mark) one would never come upon the idea of Matt 28 as a bit of patch work designed to complete the work of a source, apocopated or not.?Matt 28?is extremely well integrated into the?Gospel of Matthew itself, and is best understood as completing that work.
