Sure, why not? On the
WLP029 webpage someone mentioned using it for a stout with good results "a starbucks expresso oatmeal chocolate stout...It made the best dark beers I have made yet and definitely had a distinct German flavor."
My guess is it would turn out just fine, I'm not sure about the differences in flavor you'd get from a German vs English ale yeast.
From a BYO article.
German: more likely to get a banana/clove aroma
English: leaves a sweeter, maltier profile
Surely that is also strain dependent...and highly influenced several other factors like fermentation conditions
