Thats actually really close to what you describe that you are looking for.
Just get a different crankset and some hydro brakes and new grips. Perhaps a new saddle too (and does it really need to be all the way back?)
I also looks like the front of the saddle is higher than the rear, although it's hard to see on the pictures. Make sure it's horizontally, it will be more comfortable.
