That's exactly what I am doing now and the very existence of a dozen of "prelude" projects on hackage suggests that I'm hardly alone in that.

Except that most of them are making things *more* general, whereas Henning believes polymorphism is evil and confusing.

I use 'fmap' a lot myself. I only do not see why to alter Prelude, because you can import everything you need from Data.List, Data.Functor and friends.
