I don't have a need for such a plugin myself but I can understand the issue and technically there is no great difficulty. One question that comes to mind if someone was to assist you with writing it is the nature of the find/replace operations and how those are specified. Could you get away with substituting an entire css file? Or do you substitute just specific styles? Maybe if you could list (as an example) all of the substitutions you do currently that you require, put them either in an attachment or spoiler section for someone to take a look at.
If the find/replace operations are quite complex then you are probably going to want them specified using regular expressions for instance.
