Morphing Air Conditioner into Autocascade System

So in your opinion, propane to ethylene. Thats -42C to -104C. Or a 62C boiling point delta. Do you think a partial phase separator would be necesary? R600 to R170 is a 89C boiling point delta.

On a similar note, could you get away with strictly R290/R1150 or should you keep the R600 loop for compressor cooling and as a way to help purify the R1150 by having 2 loops to pull the R600/R290 components out of the mix?

Basically R290 -> R1150 or R600/R290 -> R290/R1150 -> R1150.

ninja-edit: Thinking about it, I'm betting the 2nd option would be better as that 1st mixture will boil somewhere close to propane, say -30C. Hopefully the 2nd mixture would boil around ethane's BP, and the final stage would be nearly pure R1150. I'm in the planning stages of my autocascade which is why I ask and I don't want to screw it up
