Yes, I built a pair years ago. I used a pair of Fostex 207E's at first then a pair of the once popular Radio Shacks (the fostex extended better and had better clarity but the cheap RS sounded better - more "musical"). They are easy to build and a nice first speaker project. But I cannot provide any info if your selected driver is a good match. You can always start with any driver and replace them with a driver up to 8". If you go bigger, jig a larger hole - if you go back to smaller build a wood cover over the hole and jig a new hole into your cover.

For wood, 3/4" birch ply for most speaker projects. I glued thick carpet behind the driver to reduce internal reflections and used cheap pillow casing fluff, stuffed very loose, in the area above the driver. I saw no point in the "wings" used in the article and also did not use the "pressure screw" although I bet it is worthwhile to try.
