That idea was actually proposed by some of our Scouts - just continue the troop but with a different chartering organization. While that sounds fine, I doubt we could find enough adult support without the push of the church behind it.
For my own personal situation as Scoutmaster, I will exit BSA on 12/31/19 over disillusionment with the girl decision. The needs of boys now bow before the god of inclusiveness, and that feels like a betrayal. It's time for me to make way for a new kind of Scout and a new kind of Scouter and a new kind of Scouting.
