I dont know if you guys would nessescarily need to change the region of the console. Just change the country that recieves that service in the XML file. it doesnt appear to be very region specific the XML file as services from Korea and Hong Kong are listed, The Hong Kong one even has an app and an identification number for that app.
so for example Koreas Kook TV the package ID is HP9000-NPHA70006_00-0000000000000100
and the file name for Koreas Kook TV is HP9000-NPHA70006_00-0000000000000100.pkg
The file name for Warhawk is
So my guess is Warhawks Package ID would be UP9000-NPUA80077_00-0000000000000083
so you could produce a legitimate package ID and download URL.
