I get what you're saying about something new, but remember that for most people under 30, "A Mighty Fortress is Our God" would be new. Even growing up in Baptist and Methodist churches, my daughters (now in their 20s) heard virtually no hymns, so we could start by bringing some of those back. They seemed easier for men to sing and (with Wesley's songs at least) usually had far more theology than we get in today's praise choruses. I like a lot of those too, so maybe a mix?
