Your 5kbtu compressor is not the best choice for propane. Different compression ratio. More in line with r-134a. Expect only half the btu capacity running r-134a through it.

My advice would be to find a used dehumidifier or window ac unit that has r-22 in it. Reclaim what you can, if you need more refrigerant use propane for the remainder. If the HVAC guy asks, tell him it's an experiment. Tell him it's a secret: you're trying to work an impossible miracle.
