As far as I know, there is no technical reason why Wayland would have better hardware acceleration.
Modern X11 compositors work on very similar principles. — the only difference is the Wayland protocol requires that there be such a compositor, and on X11 one is free to even use outdated server drawing calls that have not been used for decades.

But there is no reason for X11 to be in the picture, it does absolutely nothing other than adding another communication step between the client and the compositor.
