Margi,  I live in such a parish.  I used to think along such lines.  The English service is borderline traditional, the Spanish one perhaps also, but vibrant and exceptionally well attended.  I think there is a benefit to the participants in being able to gather without feeling need to explain or wonder if their enthusiasm is improper "in church".  I suspect the opportunity to be a community without judgement is one should not be discarded.
And after rereading your comment, I agree with the need for greater understanding of parishioners concerns, most of which are really concerns of racial discrimination combined with the cultural.  That demands recognizing the fact they have a real commitment to both cultures and "becoming American" has always been a natavist  rejection of the newcomer.
