I'm a BIG fan of different.
I did not realize this until you mentioned flutter, but there is the redundancy aspect. If the elevator (all-moving stab) were to flutter and fall off, or just plain break off, the plane would still be controllable since the fixed stab would still be there. (This is just an observation as I'm not one to include mechanical or structural failure in my designs)

Controllable?
By what?

There's nothing "wrong" with "different", but much of what you propose has been looked at and rejected as too complex, unworkable, and different just to be different without considering any actual utility.
For example:
At the top of the heap in the field of competition those sitting there are possessed of extremely find and quick minds. They look for ALL advantages over their competition, and use it.
Wierd stuff doesn't appear at the top of the heap because mostly it just plain doesn't work.. in competition.
If a specialized situation arises where a unique shape can be exploited, it usually is discovered quickly and used.
Discovering what won't or can't work is valuable though, in that it saves time for those interested in progress.
