You could write a custom Filter (or perhaps Tokenizer), but I usually just do it on the input side before things get sent to Solr.
I don't think PatternReplaceCharFilterFactory will help, you could easily turn the input into original:original, but then you'd need to write a custom filter that normalized the left-hand-side but not the right-hand-side....
