comment Homology of the fiber of a fibration
Nice question. I think your theorem has a good chance of being true. In Hatcher it is an exercise to show that $f:X \to Y$ is a w.e. if it is an isomorphism on $\pi_1$ and if the induced map on universal covers induces an isomoprhism on homology. You have the $\pi_1$ part, since the fundamental group of a $H$-space is abelian.
