Ugh, that's a *lot* of files. I can try to tackle them if no one else does, but it's going to take a while.
Nicer would be a mini how-to to edit svg(z) files. Even nicer if we eat our own dog food by using Trinity apps. The only Trinity vector graphics app I am aware (for editing, not viewing) is karbon14. I do not know what the results will be like. I'm just not a graphics person and really don't know where to start without a how-to.
I am not convinced every single image instance of a K has to be converted to a T. Possibly just deleting the K will be sufficient for all but a few of the images. Yet even to do that I am ignorant of the basics without instructions.
