Lore-wise, I think the whole "4 Daedras are fighting to decide who gets to keep me" couldn't happen, I'm pretty sure an individual would not be allowed to make pacts with several Daedras without the other Daedras he's sworn to intervening. Does Hircine want to lose you to Nocturnal? I think not, he would likely take action before you even got to the pact with Nocturnal (or Nocturnal would refuse you for being bound to another Daedric Prince).

Going to the afterlife the Aedras have for you (Sovngarde for the Nords and the valliants, for instance), I think, would simply not be possible if you made a pact with a Daedra. The Aedras are served willingly, you can stop worshiping Akatosh, for instance, and no punishment will ensue. Have fun trying to "quit" Clavicus Vile. You die, he claims your soul, that is what you get. Hell, as far as Sovngarde goes, making such a pact with any Daedra probably disqualifies you from the get go from entering. There is no honor or valor in serving Daedras.

If your Dragonborn has become a Nightingale, he is forever bound to Nocturnal. For her blessings (the armor, the luck, the power you chose upon giving her the key) in your life as a thief, she will take your services in the afterlife (guarding the Twilight Shrine), and once she judges you have served her well enough as a guardian, you will become part of the Evergloam, to be one with the shadows in which thieves hide. It's pretty clear to me. Not only does she say "The Oath has been struck, the die has been cast and your fate awaits you in the Evergloam" when you complete her quest, but even upon trying to enter Sovngarde, giving the Nightingale answer when asked by what right you claim entry ("By right of plunder, I am a Nightingale of Nocturnal") will have the guardian (whose name I forgot) note that being a thief gives you no right to enter Sovngarde, but he does comment that your oath forever binds your to Nocturnal.

I suppose an exception can be made if the Dragonborn became the Dark Brotherhood's Listener, who serves Sithis and is bound to the Night Mother. Sithis is more powerful than Aedras and Daedras (having created them), I am pretty sure he would take priority over any Daedras (and of course Aedras because you don't make pacts with them...) who thinks he or she may claim your soul. Upon dying, the Listener will, no doubt, be claimed by Sithis and become part of the Void, regardless of other pacts taken (which I doubt Sithis would let you do in the first place).
