Ideas to include fiancé's stepbrothers in wedding

[u/NMCICT544]

My fiance has two stepbrothers who are 19 year old twins. Fiance has gotten closer to them in recent years. My fiance has picked six groomsmen. We are thinking about having them as ushers. We are looking at other ideas except for readers because we are having a Catholic wedding and fiancé's stepmom and stepbrothers aren't religious at all.

For my family’s Catholic weddings, we have had cousins open the door for the bride.
