f2.8 would be too little difference from the f3.5 kit to me. I'd prefer a f1.4 and sharp wide open. Am I dreaming? There would be a great trinity: 12mm f1.4, 25mm f1.4, 45mm f1.8.

The size/weight shouldn't be an issue, the 12mm/1.4 m43 lens is fully equivalent to 24mm/2.8 FF lens. There were many 24/2.8 good small FF lenses. The m43 lens though, will have a lot more stringent requirements to the optical quality of elements and precision of assembly to achieve comparable IQ, which will make it much more expensive. So I would say there are no design problems, but high production costs would make it unattractive to the manufacturers.
