LXA as a Fraternity did this back in 1939 when TKN merged with us.
Each of their Chapters had a choice to merge or not which means that chapter closed. But at some schools it was decided if both existed they could not merge but associate with other fraternities. Only two closed down and not merge, one being in Kansas.
We designated our Chapters by the Greek Alphabet. Those TKN Chapters could use am Theta, Kappa, or Nu designation out of respect for them. We also merged some of their C of A into ours,m and part of their Ritual became part of our New Associate Ritual which is open to the public!!
