This sort of thing has been tried in the past with mixed success, but it may be a case of not giving it an extended trial to catch on.
I don't see any real downside, as we have to load some sort of scenario anyway.
However the FSO runs three frames and I'm not sure we want to have the same set up in that long.
We could run the FSO map and planeset the week prior to the first frame.
As far as the OP's specific idea, why don't we explore it?
What week would you be suggesting Waystin?
