I do NOT think it's a good idea to add fans to Karma's model, just for the sake of it. Either she should have them AND use them in her kit, or not have them at all.
I think it would be best to take the fans away from Karma entirely and create a new fighter champion, that actually uses them to deflect stuff. This would please the fans of Karma's fans.
To please the fans of Karma (confused already :P?), I would suggest to give her the power to control the twin dragons from her crest, as can be seen in her concept art. There is a lot of cool stuff you can do for her to play around with "balance", when it comes to twin dragons.
