Henrik,
You should be able to do that, but you'll be limited to displaying the data that is contained in that file (or add to it). You'd have to have wddata.php read in testtags.txt rather than wddata.txt then edit to get the right data in the right place in wapindex.php. I chose to generate a separate file so the various routines that I use on my web site wouldn't collide when trying to access the data.
