It's not so much about whether or not we want such a drastic change to the game to occur. It's about what's realistically possible to do. That's why I put forward optimizing the calendar down to 13 weeks as a possibility, because I don't know if my more drastic plan of 30 games over 11 weeks (no playoffs) with fatigue replacing game shape would be doable, much less what you're suggesting.
That's not to say that a speed server isn't possible at all. I'm starting to draw up a potential schedule in my head involving a 4 day cycle. League on days 1 and 3, NT on day 2, Cup/Scrimmage on day 4. Hmmm... would still have to find a way to fit the B3 in though. Private leagues too if you want to keep those. Result if you can pull it all off though is an 8 week season with no changes needed to game shape or training algorithms. The drawback being that not having a weekly cycle may prove disorientating for many managers, as opposed to having certain events happen on certain days.
And whether or not managers would even prefer that over a slightly slower proposal (though still faster than the current game) is unclear.
