Would it have been at all possible to get a far more centralized Holy Roman Empire out of the Reichsreform of the late fifteenth and early sixteenth centuries? Or at least, lay the groundwork for further reforms and centralization by the end of the sixteenth century (after all, with a centralized foundation laid, perhaps it might be possible for the Empire to remain a real entity if it concludes its religious conflicts at the same time as the French, and perhaps grants some form of religious compromise along the lines of the Edict of Nantes..?).
By "centralized", I mean reforming the Empire into an early modern state by the beginning seventeenth century, with a greater degree of absolutism on the part of the Emperor (along the same lines as France, with a monarch with at least as much authority as his contemporaries in the Spanish kingdoms and England)?
Obviously, there would have to be major changes implemented by Emperor Maximilian, with a considerable amount of force and strength shown by the Habsburgs, but could it be done?
