Viserys II in Essos AUs

I'm looking for fics about Viserys in Essos—ideally AUs where he doesn't reveal his identity, or does and is stuck with the Rogares etc. I think it's a really interesting 'what if' but am having a lot of trouble finding something that fits the bill.

If I have to write it myself then I will, but I'm hoping someone else has had the idea first!
