Kitty...my only concern with mixing litters is that if you have a kitten that is sick from one litter, then you can potentially pass that sickness on to all the other kittens. I typically wouldn't recommend it.
Now let's address the fact that you have 2 intact females. First, you need to keep both females indoors only and away from intact males until these litters are weaned and both mothers can safely be spayed. Cats can become pregnant as early as a week after giving birth. If neither of these cats is part of a registered/pedigreed breeding program, it would be best for this to be both these cats last litter (it is also healthier for your cats to be spayed as they have a greater chance for certain cancers when they are left intact). If you need a low cost clinic, just let me know which state you are in.
