I agree with the main premise and suggestions.
I'd just like to add that the inductance and capacitance (and it affect on high-frequency performance) seems often overstated. A good winder using suitable materials and techniques should be able to achieve sufficient inductance and high frequency extension for most common SE output requirements. A 5k:8 ohm, 35mA transformer ain't that tough.
And I'm not suggesting a "perfect" transformer can be wound, or that there is only one right way etc... that easing of inductance for a different set of compromises is not desirable for some tastes in some systems.

Follow Ups:
I don't know of any gapped output transformers that have enough inductance to prevent an elliptical load line in the presents of low bass.Let me explain a little more. I don't play bass using SET transformers for three reasons. One, not enough power, 2 too low a damping factor and 3 the subject at hand.
I have seen sims that show the elliptical load lines for a "normal" SET output transformer at low frequencies and it's not pretty. I have also seen sims of the load line when the bass is limited to 200Hz for the same "normal" SET output transformer. With the bass frequencies limited the load line almost looks like a resistive load line resulting is much less harmonic distortion.

As I said, I agree with your point in principle and would do similar if biamping. I think biamping is great approach for the reasons you suggested.
My point was that the severity and significance of some of the compromises mentioned can be overstated, especially where quality output transformers are concerned, and IME don't preclude fine or enjoyable performance used full range in a suitably matched system.
