Just a little spin I thought up.
As Ichigo lies bleeding in the street from Byakukyas attack(sp?), Isshin's senses it. He forces himself from his body, a Gigai, his reiatsu flooding back into him, and races to his sons rescue.
The rest is yours. I just think this would make a pretty hardcore fic. Isshin coming out of retirement to help and train Ichigo.
