If you watch the crash test video, the biggest issues with the Snoozer are the seat flipping over and the dog coming un-tethered. It may be that with the modifications that you have made this is resolved. You could always try contacting the Center for Pet Safety directly to get their advice.
One of the things that is a plus for the approved carriers is that the dog would remain in the carrier, secured to the seat were the car to flip. I am still getting my dogs used to their Sleepypods, but I have read a lot of reviews on the Sleepypod and folks say that their dogs really like them and are calm in them. Having always used a Snoozer, this is still a concern for me, but I am hopeful that my dogs will adapt well to the Sleepypod moving forward.
Obviously I am no expert, but just really want to make sure that I share what I have learned with everyone so that they can make informed decisions and are aware of the work that the Center for Pet Safety is doing to ensure that we all have the information we need on safety issues.
