Thats a great example of the trade off of payload vs. speed. What
about any aircraft with a 100kt+ cruise that meet the 2-1 gross-empty
ratio?

An what about the Ban-Bi and MCR 150kt cruise and 2/1 empty ratio ?
Have a look at http://www.ban-bi.com/

We're just completing an MCR4S four seater and are expecting 140 kt cruise
and just 2/1 gross empty ratio on a 100/115 hp Rotax 914.
