I've envisioned doing that sort of thing: taking a bike and replacing the engine with the engine and trans from a Ninja or CBR 250 to have a small displacement engine with 2 transmissions in series. I always assumed it would be shifted one box at a time though: ie. both boxes start at 1, shift through the first box and when it's in top gear start shifting through the 2nd box. Adjusting the final drive ratio and/or ratio between the boxes correctly should give you super high gears for cruising at highway speed with low rpm and high load/throttle opening, while still allowing a low 1st gear for starting on hills.
And in regard to fully inclosed fairings stopping on angled pavement, my thought was to use 2 front wheels close together that lean, similar to the piaggio 3 wheeled scooter, with some sort of friction lock between the two front suspension arms to lock the wheels relative to each other so the bike is held vertical at a stop, even if the road is angled.
They both work good in my head, at least!
