One way I've seen this done is to index pairs like lowercaseversion:LowerCaseVersion. You can't push this whole thing through your field as defined since it'll all be lowercased, you have to produce the left hand side of the above yourself and just use KeywordTokenizer without LowercaseFilter.
Then, your application displays the right-hand-side of the returned token. Simple solution, not very elegant, but sometimes the easiest...
