The problem I have with your data is that you'll show the exact same fuel flows for the various types, e.g, all of the B767-300ERs, regardless of power plant, will have the same fuel flows. It appears you only edit the file header information, but not the flows themselves. Granted, I've only checked a few variants, but thats what I found.
That's kinda not how it happens in the real world.
Granted, would the average simmer know the difference? Probably not. However, for those of us who do know the differences between the various variants, your data will never be in our PFPX installations...
I have the data for the B748s and the various flavors of the B787 compiled into PFPX profiles, but I only release it to those whom I know...since its obvious it came from only professional performance tools. The list of profiles I have created is here - http://www.flightsimsoft.com/downloads/PFPX_Aircraft_AddOn_List.pdf
