That would be great. We've got some basic German data that has been put together by another enthusiast out of the community-provided gliding data and some other database of waypoints and obstructions, but it's not ready for publication. If you have official data that you can work with, that's the best option of all.
If you need any help getting started with putting some SkyAngel data together, give me a shout, but otherwise just go ahead. When you've got a good collection together you can send it to me and I'll get it compiled into a .skydata file along with German roads, railways, towns etc.
I'll mention this thread to the guy who's previously put some data together for Germany and perhaps you could help each other out.
So far we've managed to stay away from charging for individual charts, but in this sort of case it may be unavoidable.
