In short Magnum, no. Aerobatics take hours and hours of practice and this means years for most people. An aerobatics endorsement, at least in my book is to teach you the basics so you can recover safely when you loose control. There are only 4 aerobatic manoeuvres, (some say 5), everything else is a combination of these 4. Like most stuff taught to beginners in aviation, it is often the inexperienced doing the basic teaching.
In order for a parachute to work in most aircraft there needs to be a method of jettisoning the doors. I think the 150 Aerobat has this. An awesome little aeroplane, but rather limited by weight. Parachutes are heavy, need repacking and checking regularly and would substantially add to the cost of basic aerobatics training. A great idea, yes indeed! Provided by basic aerobatics instructors, no.
Once you have the basic endorsement you need to practice, practice practice, then get a really experienced aerobatics pilot for personal tuition. there are several offering this, Matt Hall springs to mind. Then you most definitely will be wearing a parachute! You will also be flying something far more advanced than a 150 :-)
If I was into aerobatics I would buy my own parachute and keep it up to spec.
