What I understand from your post is actually you want to display xyz price for some country customers & abc price for some country customers. That means dual pricing method. And every other things will be same.

With default x-cart is not possible. But Qualiteam guys done custom work for me using GeoIP Country lite. So that you can configure price as per visitors country. To display currency as per country you can use multi currency module.

So instead of using x-cart on 2 different domains you can achieve your goal from single domain only which will be easy to manage
