Well everything in SS is made out of Reirokyu so affecting a certain change in the structure of that particular reirokyu using reiatsu should be possible.

Byakuya is a good question indeed, I'd like him to come back and fight rather than disappear, mainly because if Kubo didn't kill him off then, he does have a plan for him.
