We use high-mobility bilayer hole systems with negligible tunneling to examine how the bilayer \ensuremathν=1 quantum Hall state evolves as charge is transferred from one layer to the other at constant total density. We map bilayer \ensuremathν=1 state stability versus imbalance for five total densities spanning the range from strongly interlayer coherent to incoherent. We observe competition between single-layer correlations and interlayer coherence. Most significantly, we find that bilayer systems that are incoherent at balance can develop spontaneous interlayer coherence with imbalance, in agreement with recent theoretical predictions.
