It sounds like you have been doing just about all you can but here a few more things you could try:
1. Use Miracle foaming waterless cat shampoo- does pretty much the same thing as the vanilla to give them the same smell.
2. Put one cat in a carrier or cat playpen and let the other roam free. You can switch out which one is in or out. This was they can maybe get used to each other while not able to give each other injuries.
I would talk to your vet about this though...I think this may go beyond your run of the mill cat introduction. I wish you the best of luck! The most important thing is patience!
