No I do not know of a frame that would fit. Sorry. I just guessed at your weight and ran the numbers you posted. I never really thought about it too much but its funny your inseam is longer than mine by an inch, yet your overall reach is shorter, and our differnce in height is only maybe 1-1/2". The top tube on my custom frame is 598 mm.
I will ask around about a stock frames and custom ones, and contact via pm. I do not think the tube geometry would work with lugs, I might draw it up and see, also I do not think the bottom bracket shells out there will work, the most common seat tube/down tube angle is 60, not even close to 62.8, lugs can be bent maybe 1 1/2 degrees 2 max what I have been told. Tig allows any geometry, and it is lighter. Looks aside welding is a better solution for odd angle frames.
When do you need this bike? If I start asking around it would be good to know.
