I was thinking the GB may feel this is a good idea, remember they have encouraged the RF to put off having children, so this arrangement will fit right into their scheme. But the only problem if a sister become pregnant and she tell the brothers, it was a miraculous birth just like Jesus...A dilemma for the bro's, is she crazy or she had a sleep over with a horny archangel....
You know, I may be with you on this one. Thinking on gay JWs who don't want to marry anyone of their opposite sex, this may be their perfect solution.
