f/1.2 is probably too ambitious and not realistically doable. If it were f/1.8, perhaps it could be done, but the zoom would probably be too big anyway.
How about a tri-focal length lens a la Leica Tri-Mar? (http://www.photowarehouse.co.nz/leica-tr...le-finder/)
A single tri-focal length lens with the following focal lengths would be awesome (FF): 35, 50, 85. It would be f/1.8.
I wonder how big such a lens would be. Surely, it must be easier to design than a zoom while offering IQ close to prime lenses.
