We'll have to agree to disagree on that matter. If Fullbring can cause an object to move (the alcohol) or alter its physical properties (making pavement elastic), I don't see why it couldn't outright change the shape of an object; it can already do so in a way, hence the unique abilities that each Fullbringer has demonstrated. We know that inanimate objects have both souls and memories, and we know Book of the End affects the latter, so it follows that the ability should work, in theory.

What I find out of place is how he somehow gained knowledge of Senbonzakura's techniques; the only logical thing I can think of is that he gets at least some level of awareness of the memories of the person/object he is cutting, hence how he knew about Chad and Orihime's past.

Personally, a plain sword fight would have just been boring. It's clear that Byakuya would completely demolish him, a la Zommari, as you said. But I think it's more important for Tsukishima to stand some kind of chance rather than to just be cannon fodder like Giriko and Jackie. I mean, he is technically one of the principal antagonists of this arc.
