Yes, all the Jews up to that time covered by the blood of Christ under the different dispensations could be the bride represented by the names of the twelve tribes in the city. The gentiles who were covered by the different dispensations such as the strangers among the Jews who believed in the past could be the friends of the bridegroom.
I have not looked into this but even if it is so, it still confirms my theory on the New Jerusalem because the New Covenant is a "Christian" covenant and therefore WE are now viewed as the bride like the Jews were in that time period.
Don't get carried away with the past fullfilment truths you possess or you will simply be presenting a "hobbyhorse" doctrine and attempt to make everything fit it rather than allow another truth to be added, "to him which hath, more will be given". I believe the bride has been entirely made up and the marriage has taken place. Otherwise, when will the marriage occur? As an aside, imagine the joy of the apostle John at seeing his name on one of the foundation stones of the city in his vision. Awesome.
