I’ve had this thought myself – that although strictly speaking, we should want everyone in the world to be Catholic, the world would be a lot more “boring” if that happened!
One helpful thought to remember is that being Catholic does NOT necessarily or automatically mean being a Latin Rite Catholic. The vast majority of Catholics in the U.S. know only the Latin Rite, and are not aware that there are more than 20 other rites with their own style of liturgy, their own calendar of saints and feast days, their own language and other traditions, and their own hierarchy.
Recently the Pope opened the door to Anglicans who want to come into union with the Church but still retain their beautiful traditions and liturgy.
I suppose it would be possible, at least in theory, for the Catholic Church to have different rites that retained all the good features and traditions of other religions that were not in conflict with Catholic teaching. Converted Jews could pray in Hebrew; converted Muslims could pray in Arabic; converted Hindus or Buddhists could pray in Hindi or whatever their native language was. There could be a Lutheran Rite, or a Baptist Rite, or a Pentecostal/Charismatic Rite that allowed converts to retain those styles of worship AND have the benefit of recieving Christ Himself in the Eucharist.
