In a recent storyline, it has been shown that Wolverine can't identify when someone is related to him solely by his senses. 
 
Daken, and likely Wolverine, have some enhanced pheromone powers - Daken uses them to confuse people and make people sexually attracted to him (it's like he's a creepy...er... Starfox). 
 
So, here's the question - Wallflower had similar powers.  is there any possibility that she could have been related to Wolverine?  And if so, who would have known about it? 
 
In Young X-men, we were told that Beast has the DNA of X-men on hand, so he probably would have noticed if Wallflower was Wolverine's daughter or granddaughter or great-grand daughter. 
 
I can imagine Professor X and/or Scott keeping this information quiet for some reason.  If this is the case, it opens up some serious possibilities that she's not really dead (despite her body being harvested for bio-sentinel goodness in Astonishing).  Or she could recover from the dead, her healing factor just needing some time to get going???   Remember Wither did touch her before she died, so his power could have cancelled out any healing power she had...
 
OK, I'm stretching - but it'd be interesting to have a new Wolverine kid, a new reason for Wolverine to distrust Cyclops, and - generally - another dead character with amped up abilities - control over her pheromones, accelerated healing, enhanced senses, maybe superior strength and speed?  Or would she need to grow retractable bone claws for people to be interested?

raaaaah no wallflower was not family of logan
