R12 in R134 system
yes you "could" in the" r134a system" but you would have to remove all the r134a oil to do it right in which case you pretty much need to replace most of the system with new parts. you could run the retrofit synthetic ester oil and run it like that like most people do in retro fit r12 to r134a systems. but you still need to find r134a to r12 fitting that stay on the car and label the system as r12. I don't think they make.
not really worth the trouble. or cost if you want better cooling work on getting more air flow past the condesor if that means more/bigger better fans then do it. making a air dam to direct the air while driving what ever it takes

No, R12 IS more efficient per say. R134a systems run at higher pressures to make up for this fact however.
R134a systems also require different lubricants than R12.
R12 uses mineral oil for lubrication. While R134a uses PAG oil (polyalkaline glycol).
Basically the dessicants/oils are not compatible. If they get mixed/contaminated with each other, you'll either have poor or no service.
