I guess it is, fundamentally. I think that I would put it in different terms: perhaps, given a particular piece of music (nothing too difficult) what basic structure of stepping pattern might produce a simple but satisfying dance, hitting all the musicality targets (or a decent proportion of them) and not boring the follower to death.
This is what people mean when they talk about forgetting ballroom.
You are looking for a magic bullet yet there isn't one other then putting
in the time, the effort and the miles. A true non-choreographed dance
is improvised step by step in the moment and is influenced by your
partner, the music and the surroundings.
What basic structure of stepping? Look at this video and see how simply
the milongueros can move to the music but it's clearly not boring.

It isn't shuffling and it's more complicated than first it looks
but not to the lady who is a picture of calmness.
I have little doubt about how I broke through the barrier of steps
and sequences and that was by finding partners who would practise
with me because they were getting something out of it too.
First it was only technique and gradually it became dancing to the music,
many whole afternoons or evenings have passed that way in moments.
This is a dance that can be practised in the small space of a kitchen,
you have the advantage of a whole studio to play in.
Gssh says a lot more about this in his long and worthwhile post,
effectively saying there is no shortcut and I would add that the time
it takes and the improvements you make depend entirely on you.
I appreciate that there would be lots of different answers, even for the same dancers and the same piece and on the same day, but are there any underlying principles that can be brought into play, to produce a dance that isn't packed out with too much content, v. one devoid of any?
Learn how to turn simply and navigate around the obstacles, no doubt
you are good at that in ballroom yet it is different in tango.
Given the sort of music I have in mind, and given no floorcraft reasons to depart from it, a 'simple' but probably not very satisfying dance could be had from dancing an 8CB again and again, always stepping on slow counts, and so matching the music's phrasing. Given a chance, there would even be possibilities to vary the movements (or their timing) slightly, to reflect the orchestra's interpretation of the song, and if this was not a potentially 'satisfying' dance (meeting the stated requirement of using simple movements), then why not?
You can dance the 8CB repeatedly if you must and, as has been stated
elsewhere, change the tempo with the music, turn it, change the
backstep to weight changes or sidesteps. Use a tiny right foot backstep
behind the left foot for One will enable a re-orientating turn for instance.
There is no substitute for playing and exploring the possibilities offered
by not having any set patterns at all.
BTW, I don't dance the 8CB, ever, myself. I use some of its elements, but I never dance those eight steps in sequence.
You have it all about face. The 8CB has no elements that "belong" to it.
It's a choreographed sequence for easy (lazy?) teaching made up of
some of the things tango dancers may do and it's thoroughly misleading.
I've seen it claimed it includes everything but that is totally ridiculous.
Arguably the salida and the resolution are ok but the automatic cross
for me definitely is not. Not that at one time I knew any better.
My view is that when I find a teacher who teaches the 8CB to followers,
stay away from their lessons/teaching. Followers should never learn it
because the men won't be encouraged to learn to lead and followers
will automatically cross as a result of the man stepping outside.
I've experienced the dreaded automatic cross and resulting confusion.
