If you had 2 males in a room with 1 female you would have a random percentage of which one got the female(30-70 one male to the other cuz the one with 70 opened sooner) or something of the sort. Yes it will work, no it is not a good way to do it. You could have male 1 and male 2 with female 1, you get 200 seeds(really low ammount) you wouldn't know until you smoked(if you smoked the strain male 1/2 were before) or if you have grown out a female of male1/2 you will not be able to tell if it is more like male 1 or male 2. You will have female 1 x either male1 or male 2 seeds when you could selectively polinate a branch with each male and know these seeds are f1xm1 and these are f1xm2(with whatever strains you have)
