Worked around some of the tutorials and got inspired, could I get all 4 waveforms concatenated? And yes, I succeeded. Not sounding very good but when you look at the waveform in your wave editor it has sine/saw/tri/sqr concatenated.

Very interesting idea! It occurs to me you could replace the octave divider circuits with square wave slave oscs synced to lower octaves, and then you can use PWM of these control oscs to modulate the final waveshape (square waves would yield one full cycle of each of the four waves, different pulse widths might give 1.3 cycles of sine, 0.7 cycles of saw, 1.5 cycles of triangle, 0.5 cycles of square, etc.). Hmm.
