Maybe. But some features may be exclusive to the packages, and not available stand-alone, especially in some regions where packages are heavily favored (such as US and Canada), and stand alone options are few.
Another thing - the Sport+ mode for the DEC is found only on the Sport line. I doubt that it will be available ad-hoc.
