This gets back to the question I had in the 2017 thread that was never fully addressed: 3 phase balanced loading unity power factor gives constant power delivery, while single phase unity power factor gives a cyclic power delivery at twice the AC frequency. So can standard transformers perform the subcycle power time shifting required to convert one into the other?I used to be a believer in the Leyton 3-1 connection, but someone here pointed out quite effectively that although it seems to draw equal current from all three phase wires, the phase angle means that it is far from drawing equal power from the three legs.
If not, then that reflects your comment above, that while the current waveforms on the 3 phase side may be of equal magnitude, they must not be all in phase with their respective voltage (i.e. 120 degree apart from each other), as the power delivery waveform must remain cyclic at twice the AC frequency.
