Well, I'm fairly experienced, but not an expert, so ignore my 2d/2c worth if you wish...
Once you fly the aeroplane outside its design limitations all bets are off.
Discussing how best to control it if you fly with the CG outside limits makes as much sense as a discussion on how to control it with a wing off, if you'll permit a slight exaggeration to make the point.
If an out of CG limits situation is created during a flight, that's because you have made a gross and silly error somewhere along the way, such as allowing a load to shift by not tying it down properly, throwing out some passengers (with or without umbrellas) without working out the consequences on your W&B, or simply not working out where the CG will be before you start.
We could always have a discussion about the best way to control the aircraft it you decide to go without any fuel aboard and the engine quits.
To quote my CFI "If you want to kill yourself, fly with the CG out of limits. WORK IT OUT."
