I keep thinking that there's some way to do a three phase balancing RF transformer. Think of like a "neutral forming" or "zig zag" transformer to force 3 phase balance. then you'd drive one of the primaries, and let the transformer force the other two to be in triple phase.
With just an ideal transformer there is no way. Single phase to three phases means that at the nulls of the input there are outputs at at least two of the outputs. Some form of energy storage in reactive elements is necessary to obtain this.

Or, some Delta connection of Ls and Cs to create an appropriate resonant configuration. The problem I see is that with 3Ls and 3Cs you have 3 (at least) resonances, and getting them matched is impossible.. So you want some sort of scheme that forces the 120 degree phase shift.

This may be possible. Something as a single primary capacitor feeding three Tesla transformers through LC phase-shifting networks, so the three outputs grow simultaneously, with the same amplitude but with different phases, with identical energies. An adequate structure has to be found for this, but it seems possible. The main complication of the idea is the unavoidable magnetic and electric coupling among the three secondaries at small distance, that is difficult to model and control.
