The Mass Effect 3 Ending i Would Have Liked to Seen

First off, no i haven't played Mass Effect 3 (i did play the firs two games of the series).  Without the backlash from the "scorched earth" ending, i probably would have purchased it (and beat it) by now.  As it stands, i guess i can wait until it is deeply discounted (i got Mass Effect 2 for $9.99).  i disliked the demo - the ending controversy was icing on the cake.  i guess i will just spend that money i would have spent on Mass Effect 3 on The Witcher 2 (despite misgivings on difficulty).
My Ideal Mass Effect 3 Ending(s) - some random notes:
*  i want a "happy ending possibility" that is an option, not the only one - of course my idea of a happy ending is to repel the reaper threat (and have them retreat, after taking care of Harbinger).  Let the civilizations 5,000 - 50,000 years from now deal with it.  Let the Quarians set up their new planet and the Krogans deal with life post genophage. Let Shepard live "happily ever after" with his/her love interest (maybe raising a family).  i could deal with a few systems/planets being wiped out.  i mean, Pluto's status as a planet has already been wiped out. 

* i want a bad ending too, where the Reapers win and galactic civilization is wiped out completely.

* Ending possibility 3: the sacrifice ending.  i'm ok with that option of Shepard somehow sacrificing himself or (the Normandy with crew on board) to save everyone else.  Like the Star Ocean: The Last Hope character who created a black hole to deal with the boss. 

* Boss fight with Harbinger - i don't view boss fights as "too video game-y" for a video game. 

* War Assets should actually mean something.  i want scenes of Rachni swarming a reaper, i want the Destiny Ascencion to come in and help me with its massive gun, i want to see the Quarians defending their new home planet, etc.  Admittedly, this may not be easy to implement.  Not every race needs to hunker down around Earth (they could have their own problems to deal with).  Some war assets should play out in the final boss fight. 
- Effective Military Strength should be jettisoned (multiplayer should NEVER impact the single player expreience).
* i want to see the citadel annihilated by the Reapers, destroying the catalyst (forcing the races to depend on themselves - not deux ex machina).
