I think its pretty obvious that Ichigo will regain his powers through Isshin's guidance. Not only does it follow the show format but it gives Kubo a way to show isshins past without diverging from Ichigo's story for the following reasons. Throughout Ichigos training to reclaim his power there could be intermitted flashbacks to Isshins past and how he had to use the FGT and why, this will let us know about Isshin but at the sametime allow Ichigo's progress to continue. Also if we think about it Ichigo at somepoint is always helped by a mentor, at first Rukia helped him to use his new shinigami powers, then Urahara helped him reclaim them and handle them better. Later it was Yoruichi who guided Ichigo towards Bankai and then Shinji and the Visoreds who helped him control his Inner Hollow. It would totally fit the format for an older, more experienced person (Isshin) to help Ichigo through a rough patch.
