Bar Mitzvah for an Ashkenazi in a Yemenite Synagogue

I am Ashkenazi and my wife is Yemenite, and we celebrated the Bar Mitzvah of our older sons in an Ashkenazi synagogue. Our youngest son has a strong connection to his Yemenite grandfather and the Yemenite style of reading, as well as the Yemenite synagogue near our home. He wants to have his Bar Mitzvah in a Yemenite synagogue, and he has even started studying the Torah portion with his grandfather using the unique Yemenite pronunciation. My question is whether there is any issue with this according to Jewish law.

Dear …! <br>There is no problem at all in having the Bar Mitzvah in a Yemenite synagogue, and having the son read the Torah with Yemenite pronunciation. However, it is preferable for him to recite the blessings in the pronunciation of his father's tradition. <br>Although the son's custom follows that of the father, regardless of the mother's lineage and background, it is very important to connect the son to the synagogue. If he feels more connected to a specific style, it is important to have the Bar Mitzvah ceremony in that style, especially since his grandfather is teaching him and passing on the precise heritage of the Yemenite Jewry. May you derive much joy from your son, and may you merit to raise him to Torah, chuppah, and good deeds.
