That would be nothing more than a stop gap solution at best and it still wouldnt change the basic fact that your enemies/potential enemies have more modern tanks that outclass yours,I`m afraid that doing some basic upgrades on late cold war t72s isnt going to make them a match for leclercs,late model abrams and late model leopards and even an indigenous tank program will likely take the better part of a decade,assuming that the design is actually successful that is,before it would start to go into service so what are you going to do for that time period?.The sad fact of the matter is that irans armored forces are just like its airforce ie outdated,decrepit and badly in need of brand new modern equipment.
