That is an excellent thought, John Mack, and is one under some active consideration by a number of apostolic religious orders.  The start of just such a religious community can be found in a good number of communities that have "lay" communities of married couples and even whole families who are part of a broader religious community on an equal basis with vowed members, who take religious promises after a period of formation, and who have a charism that is complimentary to that of the vowed religious.  It is pretty impressive to witness.  So, you are right on the money with your foresight and I am pleased to share the beginnings of the actual developments with you.  Many blessings to you.   And I have the feeling that the Beguine movement will emerge once more.
