Here's what I'd do:
Grab some of the fan scenario downloads that are in English (email me or send me a message know if you can't find them) and let google translat them for you. That is a very quick process. It's what I do for your German scenarios and even the French ones.
Here is the latest batch of scenarios from Germany: http://www.soehne-sigmars.de/2012/07/szenario-wettbewerb-august-2012/
Then follow up on this site: http://www.altewelt.net/viewforum.php?f=6
There are many scenarios that can quickly be translated with google translate. It's not perfect, but can break that log jam in your mind for new ideas. Here is a link to the scenarios: http://gallery.rptools.net/d/82966-1/WFRP+COMPLETE+SCENARIO+LIST+AND+DOWNLOAD+LINKS.pdf
