Approve the idea but maybe tone down the penalties. Also, none of greatweapons have extra range naturally.

The Huge Blade is already in the game, and already does all those things other than make a weapon count as a greatsword. The rest of the suggestions are clearly modelled after it.

This sounds like a good idea, even if only for flavor. We have so very little that interacts with weapon subtypes that anything that allows any synergy of it is great.
