It will be , I'm currently developing some child styles on it, it's honestly the best way to make sure the parent is setup to be nice and easy to customize. The bonus to that is it'll ship with the child styles as well which will have an alternate look.
I need to do something to my sites on style as I'm getting little issues here and there that are not getting resolved. None of the PE styles really fit, and I think this one might.
If nothing else, I'll just be forced to update the Apex license and go with it or grab Adara.
