I solved the state you were talking about.
The solution would like like this (similar to what you wrote):
stream.keyBy(...).timeWindow(...)
.apply(new WindowFunction() {
public void apply(K key, W window, Iterable<IN> elements,
Collector<OUT> out) {
out.collect(new Tuple3<>(key, window, elements);
})
.keyBy(0) // use the same key as the windows
.mapWitState(...) // process the windows with shared information
