Most likely he would have had a hard time, but there's no telling that he would definitely lose. Kubo never put Byakuya up against Wonderweiss. Predicting the outcome of a pairing that never happened is difficult.

It was said that Byakuya was one of the most skilled Shunpo-users in the Soul Society, I think he would have been able to hold his own against Wonderweiss at least a while.

Kensei lost to him, but he was more the kind to use raw power than speed.
