Sure, no problem, but why not just use the KFileReplace plugin? It does it 
elegantly with multiline replace, backups, directory control, wildcards, 
saved searches and more.

I haven't had to use KFileReplace's more advanced features a lot lately, but 
unless recent code cleanings have stripped out features it does handle multi 
line code and I thought it had an elegant way of handling strings and pattern 
recognition and rewriting. I guess I should go look at it's pattern matching 
abilities. I'll have to check to see if features got removed in rewrites.

You're of course welcome to build a Kommander based tool using PHP and even 
make it available via KNewStuff.
