A friend of mine likes to identify himself as Pastafarian. I've read the whole FSM Gospel.
Morality on that standard can indeed be derived from such events. However, this is an idealistic view of morality. The world as we know it doesn't work that way, and only the really virtuous (virtuous as defined by Aristotle) would be able to naturally embody such a form of morality. In reality, and this is the blunt truth, people are naturally pre-disposed to be self-centred. Every action undertaken is a way to pleasure oneself or to conform to societal norms and preserve the status quo, and ergo happiness(stability) of society, which then leads back to the individual's happy life. For example, giving change to a homeless person, you may either feel happy at having done a good deed, or you may feel happy that people have seen you do it and now see you as a relatively decent person and thus raise the overall happiness or society.
On the other hand, what you're describing, and this is what I assume you're describing, is that any objective action for the greater good is good. Like I've said, this type of morality can only truly exist in virtuous people. For instance, take the scenario of a nuclear holocaust in which the only survivors are eight children and eight adults. There is only enough food to feed one of the two groups. Now, imagine that you can only choose to feed one group. (This is a thought experiment to test the boundaries of your view of morality so just ignore the logic of the situation and concentrate on the dilemma.)
In normal morality, feeding the children is good because of all the moral dilemmas involved in killing children. Nietschean morality mostly deals with survival of the fittest so we won't use that. In your morality, however, killing the adults is bad. The children won't survive on their own anyway. Letting the adults live is 'good' because the species benefits as they can procreate. Children can't.
So yes, in conclusion, this kind of morality can exist, but, in certain cases, it conflicts so much with regular morality that practicing it is hard. Other examples deal with the greater survival of the species being too far out of the scope of normal people to notice.
