Although they have a similar look on paper, I don't think they match. They don't mismatch either though. I'd prefer Talia over Talya, but with Faye the -y- spelling might be better.
I like it, I think they go very well together yet still have their own unique charms. The alternate spelling Talya is a good choice paired with the modern-sounding Faye, as opposed to the more traditional Talia.
