The wings look good. You're frequently better off building tools like that yourself as they are built to suit your individual needs rather than having to settle for or adapt your work to a mass produced product. A stand like the Stablemate you are using or the Dewalt or Ryobi stand shown above make great bases for the wings with the added advantage that you can use them for small in and out type jobs without the wings when they aren't necessary.
I prefer wings to be wider than the ones you have pictured as I frequently use them as a work surface for coping, scribing, and occasionally pre-assembly. The fence on the wings allows for the use of flip stops and I prefer them to be set back from the saw fences which is another reason why I like a wider wing. I copied Katz's fences when I built my stand so that they telescope out to allow for repetitive cutting of material that is longer than the wing. You can do it with t-track or there are plans in his book to do it with a t slot router bit. The disadvantage is that if you wanted to add a tape measure to the fence it is more time consuming to dial in. I don't use thae tape and just set my stops to the pencil mark on my first cut. I have and use the Kreg flip stops but don't really trust them 100% as they flex if hit to hard ( it really doesn't take much to hit them too hard) and tend to creep a bit when you tighten them down . The production stops work well but they are limiting. I frequently have half a dozen stops set up at any one time. I plan to make my own flips when my schedule eases up a bit.
I recently rebuilt my wings and added t-track going cross grain to attach a continuous crown stop. I have found it to be well worth the extra effort as the stop is easily adjustable without having to screw around with screws or clamps. It also makes it easy to attach jigs for cutting acute angles, rabbet panel moulding and radius trim.
Good luck. Post a picture of the finished product.
