Hi Aaron!
Wow... okay... so, mains come into an autotransformer in Delta and the output goes to a step down that is also delta... and that goes into the bridge rectifier, but not before passing TWO of those leads through FUSES???
The resistance ribbon on the autotransformer tells me they're using that as the enforcer of 'slope' character.
That's all so wierd, that if I were in industrial espionage, I'd write that off as being intentionally drawn wrong, so that anyone reading would be led astray from the 'real' design. Either that, or the draftsman was harnessing his inner Escher...
As for possibilities, I have no idea how well it would work. From a simple standpoint, running the autotransformer input as I explained the CP-series, the OTHER side operates in a sequence, however, it is doing so in quadrature... 90 degree alteration segments, rather than 120, so the output would be at a higher frequency by 4/3rds (80hz), and that step-down transformer might not like that at all... it's an inductive reactance element... so it will take empirical evidence to answer that firmly. I do know one thing... if you use too much capacitance on the input of the autotransformer, it'll melt out a primary winding really quick, so be careful and start at like... 15uF, and creep up slowly from there.
