Oh yeah, I did the same thing. That $170 driver costs $260 in places like HI/AK. When A 15" with 14-15mm xmax can be had for around $150 (or less) shipped, it's really a no brainer.
Thomas, with the pair of 4" x 23" ports added you will be left with 8.16 ft3, the woofer's going to use up around .1 ft3. Going slightly under 8 ft3 wont be a big deal, just make sure you're not wasting space with the braces. Picking up some .75" thick dowel rods to make the bracing will save a lot of space vs typical mdf shelf braces.
