I like all of that stuff and I believe all of it can be accomplished without any lifting of the fingers.
Yes and no.

I think it works both ways. You can have:
1) an arsenal of movements you have learned or found
2) an arsenal of sound quality images you can choose from
Different types of movement necessarily create different sound images, different overtone qualities, etc. that can not be achieved with certain other body movements, however hard you try. If you are a good pianist, you can readily choose which movement is most appropriate for which sound effect you have ever encountered. On the other hand, if your imagination and urge to create something new really guide you, then a certain sound image may give birth to another physical approach.
If your philosophy is to ALWAYS stay near the keys, you will be limited somehow in what you can do in terms of sound effects. On the other hand, if your default way of playing is swing with the fingers and lots of body weight behind it (Arrau, Rubinstein) to get a massive tone and nothing else, then you will have a hard time getting the effects a Michelangeli or a Horowitz creates, etc.
Herein lies the tragedy of all those alternative piano methods: they teach you how to move "properly", but the artistic results are often poor because other ways of moving a key are taboo.

EDIT: Here, especially for you, is Michelangeli:
Look at how he swings the fingers of his right hand into the keys and what magical effects he reaches by doing this. Try this at home and then try your default of staying close to the keys. That last approach won't cut it if you want this heartbreaking effect, really.
