Rebel the Wolfgirl

OK, so here's the title and synopsis for my Madoka fic:

Quote

Puella Magi Kurumi Magica

Set in the post-Madokami timeline (and explicitly ignoring the events of Rebellion, instead opting for the manga's ending of Homura joining the others in Magical Girl Heaven), this fic is very much a reconstruction in the same vein as Mobile Fighter Evangelion; following a new group of magical girls - the eccentric and crass bosozoku Kurumi, the cynical misanthrope Chika, the hotheaded Kaida, the flower child Fuji and young wallflower Sueko - recruited by the enigmatic Gobey to battle the wraiths plaguing their city. But of course, while this might be a far lighter and softer setting (I'm taking inspiration from early Kazumi Magica for tone), this is still Madoka Magica we're talking about - there may not be the risk of witches and Gobey is a far straighter example of the mentor mascot than Kyubey was, but the darkness of the setting is still there, if not as prominent.

 I am still stuck on what each of the main girls should wish for (since that determines their powers). Also, can I assume that Soul Gems still need to be purified in the post-Madokami timeline; just not with Grief Seeds (since witches no longer exist and if you want to get into the technicalities, never did), but with the little cubelike shards Wraiths leave behind according to Homura and Kyubey's final conversation?
