Conversion R134 to Isceon or a Hydrocarbon based refrigerant

I would like to convert my C5 from R134 to another refrigerant and in the process change the oil to a PAG oil.
As far as I can see the benefits in doing this are win! win!

Question has anyone done this if so what did they use, what problems if any did they have, what oil did you use?

A proposed replacement gas, for new cars at least, from 2011 in the EU is HFO-1234yf

Yes Du Pont's last hope, but cars are going into production using R 744 (Co2) now. Whether HFO-1234 will come to pass is an open question but as far as I can see as a refrigeration medium it is no better than R134 and I believe will still have most of the disadvantages of R134.

My main aim is to get away from POE lubricants and get back to PAG or mineral oil lubes. Bigger molecular size would be a bonus.
