At the end of the day if you're comfortable that is all that matters really. If you rode a smaller framed bike you'd no doubt still have the seat and bars set to something like the levels you have them at now. All you're doing is filling the `air space' that a smaller frame would give you with frame, for what would be effectively the same riding position.
In conclusion, bike size/fit looks good. Let your body and your riding tell you what is right, not what the `experts' tell you to conform with today's trend for an aggressive/competitive fit.
I have always ended up with the "next larger" frame as they seem more comfortable. If you are going to use your existing drivetrain and components, what's to lose except some bar tape and cabling? Seems a science experiment might be appropriate just to answer your curiousity.
