I doubt the spirit of the arrangement would change much, maybe they might change the name and change how they are being reimbursed (put the financial load on one or more of the congregations directly).Maybe they toyed with the thought in their ivory towers but the matter of fact is that they need those yes-men to reinforce "good practice" in the elder bodies or they would veer off, see Menlo Park for example.
In some congregations even with the browbeating every 6 months there are major issues in the elder bodies allowing homosexuality and promiscuousness, not handing off forms correctly and missing paperwork especially if the elder body has nobody older than 50.
