"quicquid Latine dictum sit altum uidetur"
Shouldn't it be quidquid?

"Ego Rex Romanorum et super grammaticam sum"
Shouldn't it be "super grammatica", as in ablative? super + accusative, if I recall correctly, is "move up towards"... "staying above something" should be ablative.

Both might be mistakes by my part, as it's been about 10 years since I last studied latin.

And apart from those two nitpicks, great idea and a commendable effort. Grats and thanks, I am sure many on this forum will find your offer useful!
