Don't forget that the Grimm Bros. themselves started to bowdlerize some of their tales because of this reason. A good example is Rapunzel.

Oh, I know... But the interesting thing about the Grimms' retellings is that they put out seven editions of their collection between 1812 and 1857. Here is a paragraph by paragraph comparison between the 1812 version and 1857 version of Rapunzel translated by professor D. L. Ashliman.

He has the same sort of comparison for Hans my Hedgehog... and no fancy coat appears in either version. Then again, for some reason, the translation we used in class was of the 1819 edition (perhaps because that was the largest edition [?] 210 tales, total), so maybe they put the coat in, then took it out again... But I find it unlikely that they would make the story more violent in the final version when they had edited out that violence in the second version... but maybe...

In any case, they set a precedent that makes me more comfortable with making changes of my own... especially when their heroines are too much like glass figurines to be believable...
