Zhou Yu's plan was, I think, heavily flawed. The historical Liu Bei was way too politically astute and ambitious to be lured by luxury, and would probably sense the trap(to better illustrate the point, think of SGYY Xuande as a domesticated turkey, pretty dumb and slow-witted, and SGZ Xuande as a wild turkey, wily and quick-witted). Plus, Zhou Yu's plan comes into competition with ZGL's Long-Zhong plan, and this could cause the detioration of Shu-Wu relations in almost the exact same way the infamous Jing situation did later on. Plus, I would like to point out that Shu and Wu, at this time, had a similar amount of talent in "high"* positions, and it took Liu Bei a couple years to conquer Yizhou....and he started INSIDE Yizhou. Zhou Yu would have to attack through Yong-An, which proved to be a nearly insurmountable task for Lu Kang some 60 years later, and that venture was ultimately abandoned with little or no gain.
*I'm not saying that Wu had the same amount of talented officers as Shu at this point(rather, I think they had more throughout the period), but people like Lu Xun, Lu Meng, etc. were still in minor posts, and, as history showed, didn't make much of an impact until later. By comparison, Shu had Zhang Fei, Pang Tong, Huang Zhong, Fa Zheng, Zhuge Liang, and Liu Bei himself playing roles in this invasion.(I would mention Yunchang, but his talent is highly debatable, and I believe he was at best an average commander, but a good warrior.)
Landing the first blow is nice, but only the blow that counts is the last!
