Franky1 is the biggest advocate of this idea in the forum. I respect that, but it is very debatable. What if Bitcoin Cash increased its block size and doubled its monetary supply? Would that "bilateral split" idea be easy to accept? I believe it won't.
If it increases the block size and total supply will make things worse. If this happens, will the price drop by half? And who are the owners of the supply of additional supply? Who owns it get benefits from this? Any reason I believe in this?
