Sorry about the delayed response.
I can't see a way to easily solve that problem with a filter. Meld's filters just remove text, they don't let you alter it... Otherwise it might work out.
Enhancing the filter system is a long overdue job, and the filters themselves are very simple, but interactions with the comparison are nasty. However, I think that a replace-style filter would definitely be a sensible future project.
