Default [Q] appear as different device to certain apps

I am looking for a way to have my tablet detected as a different tablet (e.g. Nexus 7) in certain apps (BBC iPlayer, flixster...) because these apps don't allow video downloads with my tablet (ASUS memo pad HD 7) but do on other devices.

Ideally, an xposed module to let the tablet be detected as a nexus 7 in those apps and as normal in other apps would be great, but if there's another better way to do it please let me know.
