If it was profitable then yes, sell off and "reinvent" or keep the ones that you do not like/are duplicated and stop contributing to them.
It helps if you theme your portfolio meaning: 80% offshore, 10% local, 10% property... or in your case 80% (50% developed markets, 20% emerging markets, 10% tech stocks), 10% local, 10% property. Get the "theme" right so you know what you want to do and then use the appropriate ETFs to do so.
