Convert multiple FirebaseObjectObservable into a FirebaseListObservable

The snippet is part of a bigger code. Generally I have an object on firebase database called users (it's not a list). I need to get some of them and then convert into Array or FirebaseListObservable.

Observable.merge(...[
  this.db.object('users/user1'),
  this.db.object('users/user2'),
  this.db.object('users/user3'),
  this.db.object('users/user4'),
  this.db.object('users/user5')
]).subscribe(user => {
  console.log(user);
});

This return me user by user, however I need to get all users together. I need to do it in sync. Any ideas?

I have a similar problem and this is how I'm solving it for the moment:

getUsers(): Observable<any> {
    let observables = [];
    for (let user of users) {
        observables.push(this.db.object(user))
    }       
    return Observable.combineLatest(...observables, (...results) => { return results });
}

What I did not manage to do is to return it as FirebaseListObservable.
