It is impossible as they come from 2 different companies: HiTechnic and Lego. By the way you come from Tassie? What a nice place! I was recently in Hobart last August for an exchange programme. I am actually born in Carlton, VIC. I am sure that you are asking this question for the upcoming RoboCup Junior. Good luck and I hope that if you win this competition, you would proceed to WRO Moscow.
I remember asking the hardware devs about this and I don't think it ever occurred to them to make the LEGO IR Sensor work with the standard IR balls. The HiTechnic IR Seekers work ok with the EV3, though.
