Java custom function on stream

Question

Say I have something like

something.stream()
         .filter(filterMethod) // Same
         .map(mapMethod)       //
         .map(somethingElse)
         .filter(filterMethod) // Same
         .map(mapMethod)       //
         .filter(otherFilter)
         .filter(filterMethod) // Same
         .map(mapMethod)       // 

Could I create custom function on Stream and convert .filter().map() to one method? Implementing own Stream seems to overkill. It would be nice to have some short lambda function or method like

Stream<T> fooFiterMap(Stream<T> stream){
    return stream.filter(filterMethod).map(mapMethod);
}

and then reduce my something stream into

something.stream()
         .fooFilterMap()     // New
         .map(somethingElse)
         .fooFilterMap()     // New
         .filter(otherFilter)
         .fooFilterMap()     // New

You can obviously write your own one:

<T> Stream<T> fooFiterMap(Stream<T> stream, Predicate<T> predicate, UnaryOperator<T> function) {
    return stream.filter(predicate).map(function);
}

But the real question is why? It's too verbose? If so, than I'll argue - I like the chaining of filter and map more - bit it's subjective I guess. If you think about multiple objects created, than just think about the fact that these are probably stateless lambdas used on the same call-site, thus a single instance of Predicate and Function.
