I do not understand what you mean by keeping the same topology. If you currently have a group of machines (LNX1, LNX2, and LNX3) and you clone it to create LNX1A, LNX2A, and LNX3A) but connect them to the same broadcast domain (whether you create a new VSWITCH on the same OSA CHPID or use another guest to bridge between two VSWITCHes) the new group is now in a broadcast domain with the original group. If that is not what you are trying to prevent, you could just add the new linux machines to the original VSWITCH. I think I am misunderstanding the purpose of breaking them into distinct groups.
