yes they probably would mate..
What are the ages of your 2 leos.. if either one of them are too young then your leo could be damaged by the other.
also i wouldn't recommend keeping just one female with a male. as he would no doubt stress her out causing her to become ill.
feeding may also be an issue as the female may not get the right amount of food due to the male taking it all.
I am in no way saying that keeping males and females together is bad i am just making sure your leos will not be damaged by doing so..
another important factor to consider is the tank size. is it adequate for 2 leos the amount of furnishings?
If you still want to put them together make sure the leos are both of good age and the enclosure is large enough for 2 leos (even better 3) and make sure there are plenty of places your female can hide to get away from the male if needs be..
ask more questions if need be.
