Topcase and Keyboard replacement for A1369

Hi,

I am about to change the topcase of my MBA late 2010 after a damage, caused by an entire glass of wine. At the beginning it was pretty bad but I could dry, clean all parts and finally start it. Still the keyboard is damaged.

Now I would like to buy an english top case -a lot cheaper- and replace the current german top case [including keyboard]. The track pad will remain the same [german]. Does anybody know if there might be any problems related to the english keyboard on the german MBA? It shouldn't matter if the trackpad is from the German top case right?

Kind Regard and thanks in advance
