Well I just had a cool idea .. well at least I think it would be kinda cool ! The Idea is that maybe instead of summons or something like this they could give sora the ability to switch to Roxas or Xion ! what I mean is .. maybe the two can´t be restored but Sora kinda gets the ability to switch to one of them for a amount of time ! like you switch and they kinda switch hearts and with it the body ... for example you play with sora ( normal ) and switch to Roxas ( most likely dual wielding ) or you switch to Xion ( maybe she can partly transform her body to her other forms ) Soo it´s very very unlikely to happen xD but I still wanted to share that idea and hear what you think of it
