Can my dwarfs be housed together again?

My 2 Chinese dwarf hamsters sadly began to fight, and i am wondering if they can be housed together again as i am buying a new cage, and ive heard that you can put a net to seperate them and they will like be intreged by each other and sniff each other etc etc? so basically my question is, can they be housed together again? or will they go for each others throats all comments are appreciated, ty =)
