Hello Tom! 
what is the problem of mixing them? you mean you are afraid that they will fight?
If this is the case,I suggest that you put the new ones in an acclimation box,in the aquarium where yours GBR are.And see how they react with each others.I used to do like that when I want to introduce a new female to a male betta,because the male if he doesn't accept her,will kill her or worse she will kill him
