White is NOT removable either, I'm pretty sure if it was, then Vizards would've gotten rid of their "inserted" hollows, (whereas Ichigo was already born with it), the lack of White's presence within Ichigo would've killed him, because of the "soul suicide".

For reference, read http://bleach.wikia.com/wiki/Hollowfication White would be the cause of soul suicide not a lack of him and since he was created with shinigami souls (unlike visored Hollows) he should be removable like how Rukia's Shinigami power was forcibly removed from Ichigo by Byakuya.
