if you get a good quality radiator and condenser plus a very good and high CFM and RPM fan then it will suck more air from condenser and radiator which will improve cooling. plus if you exchange the location of compressor and alternator then it will improve cooling while car is moving; compressor will not get much hotter.
if you look at coure's system then it has compressor infront of car and alternator is at back plus the fan of coure is very powerful; it can move massive amount of air.
so you basically need to first get good compressor preferably of some japanese used car. then a very high CFM fan, good condenser and radiator plus a good technician to do the job and ac cooling will be just like coure or even better.
