Cool! I could help you with that.. but what i honestly think is that this tweak should be possible on any theme. It would probably be pretty easy to do. I could teach you if you'd like. A couple of seds for any string you need to change.

The sed command goes in to a file > finds the string > substitute it for what you like. So if you want a value be changed from "200" to "100" you would do "sed 's/200/100/' /path/to/file". That sed will not write to a file so feel free to test it out. To write to a file you'll need to add the "-i" prefix. So pretty basic and with some variables it would be compatible with any theme.
