Unfortunately, chemistry would thwart your efforts. The binding of proteins to other molecules (like sialic acid) is a reversible process. In other words, it's not as if each Hemaglutinin binds to a single sialic acid molecule and that's it. Each Hemaglutinin is constantly binding and unbinding, so adding extra sialic acid might slow down the process of fusing with the host cell, but it wouldn't prevent it. Actually, the way that the current antivirals work is sort of the opposite. When the new viral particles are emerging from their host cell they end up stuck on the sialic acid molecules on the surface. That's where the Neuraminidase (the "N" of H1N1) comes in. It's job is to cut the new virus particles free of the host cell that produced them. If you block that, you can effectively stall the infection before it gets started.
