First, why isn't she spayed? I'm more worried about the fact that she's pregnant than the fact that she only eats Fancy Feast. It's not healthy for her to be pregnant and to keep going in to heat. It's going to be awfully expensive to spay and neuter every kitten she produces (not doing so is incredibly irresponsible), not to mention finding good homes for them.
I looked at the pictures of your kitties and they are beautiful. I'm concerned because it doesn't sound like you have an actual breeding program or a mentor or even if they are registered with papers. Did you have them genetically tested before breeding? Do you have the breeding rights for them from the original cattery you bought them from (assuming that's where you bought them).

This is for dogs but applies to cats as well:http://www.jlhweb.net/Boxermap/reputablebreeder.htmlhttp://home.comcast.net/~NoPuppyMill..._breeder_.html

A simple google search will lead you to many reasons why she needs to be spayed, but I realize that you are seeking food advice.
So as far as the food is concerned:
- She needs to be on kitten food while pregnant, not regular adult food. Fancy Feast is all-life-stages but I would try to find a kitten wet food, like Nutro Max Kitten. It's the same price as Fancy Feast but better ingredients and cats seem to like it a lot. It might just be that you have to try a lot of brands to find the right one. Or sprinkle parmesan cheese or catnip on the new wet food. My kitten doesn't seem to like wet food so I sometimes sprinkle the dust from freeze-dried chicken (like Halo's Live-a-Littles, they have them at my PetCo) on to the wet food. I know you said you tried mixing. Maybe try mixing human tuna with the new wet food? Also maybe heating it up a bit would help.
- As a general rule, I think that wet food is better than dry food. It's not really a bad thing that she only eats wet food. I would just try to wean her off of the Fancy Feast (a.k.a. Kitty Crack). There are so many higher quality food options out there. Does she like the flavors with gravy? Pate loaf style? Chunks? You might have good luck with the pouches instead of cans.
I'm not sure what types of pet food stores you have where you live, but at PetSmart I would check out Nutro Natural cans and pouches, Nutro Max cans and pouches, Authority cans, Avoderm cans, By Nature Organics cans & pouches, Blue Buffalo Spa cans. I would also consider trying Meow Mix. It's not really the same as the other brands I mentioned, but it's a little better than Fancy Feast and she might like it. Meow Mix makes pouches and cups.
PetCo carries most of those brands I listed, and also Natural Balance (which you tried).
If you have a small independent pet food store by you, look for brands like Wellness, Evo, Innova, Chicken Soup, etc. I have a feeling you might have less luck with these than you would the the easier-to-find foods I just listed. That's just based on my own experience with my own picky cats. These particular foods are very good but also very rich.

It's not even just about the mercury or the fact that a high-fish diet can lead to urinary issues. It's that the cat is not eating a well-balanced diet and will not be getting important nutrients that are added to cat food. It'd kind of be like eating only oranges for your whole life. I feed my cats human-tuna as a treat maybe once a month, if that. I give them little pieces of plain chicken sometimes but always as a treat.
