I think the discussion of changing the forum should be decoupled from the question of moving the forum.
I think most of us probably would like to change the forum. I think most of us would also be quite pleased if the forum in its current form continued to exist for another week, another month, another year. If it never changed again, we'd probably all be happy to have it in its current form, than not at all.
So I think that the middle of a momentous, contentious moving of the forum, we find ourselves at the worst possible time to also debate changing the forum. Let us not multiply entities unnecessarily!
Let us focus now on the matter at hand: the unavoidable moving of the forum. Since we are all agreed that the forum is desirable in its current form, let us focus on moving it in its current form.
Later, after the dust has settled, when the forum is under new management, and we have satisfied ourselves that nothing of value has been lost. Then--only then--should we take up the question of how we wish to increase the value of the forum by improving on its current form.
The romantic in me says that we should wait a year and a day from the move, before we take up any question of changing the MA, offering an amnesty, etc.
