Personally i think this is a very bad thing to do. 

Wallpapers are optional and have nothing to do with development, so having 
them in a remote place is ok.

kdegames data is a integral part of games (most of the times you can not use 
them without the data). Keeping them in a separate repo is going to make 
maintainance harder and the random volunteer contributions much more scarce 
than they are now (since they will have trouble getting the game even to stard 
and move their focus somewhere else)
