Perhaps the introduction of more beautiful/traditional music, or incorporating sung or chanted portions of the mass. One example of the sort of thing I’m talking about is the daily mass on EWTN, where the congregation chants the Pater Noster. Also, during communion and the meditation period after, there could be one or more sacred hymns or songs performed to help the congregation more profoundly reflect upon the mass and the Eucharist. I would be careful deviating too far from the traditional mass structure, as this could turn into more of a distraction from than an aid to worship during the mass. Also, correct me if I’m wrong, but I think I remember that only priests and deacons (and those superior to them of course) are allowed to give homilies during the mass, not lay people.
God bless!
