This is certainly a sensible option, but at the end of the day many systems designed for R12 will simply not provide ice-cold air when refitted to work on R134a.
My 1992 Opel Omega Caravan 24v has been retrofitted to R134a and on very hot days (ambient temperatures exceeding 30'C) it takes very long to have the car cool down to a comfortable interior temperature. The system is 100 percent leak-free, with many components having been replaced recently. The conversion was performed by a previous owner - if it were for me to decide, the a/c in this car would still be running on R12, like my 126 does.
