Hhmm... On that last wish, you might could find a decent Honda CX 500 Turbo (I think I got the model right), graft the right front end on it, play with the seat and subframe maybe, and end up with something close to what you wish for. Think in terms of smaller lighter and more tractable version of the Guzzi Quota.
Single track carver - not. But dual sport which keeps going when the pavement stops - possible.
Going back to the Dark Ages when I started riding, all motorcycles were dual sports. You took them anywhere they would fit, would climb, would hopefully get back home from.
There's potential out there sitting in barns, sheds, and the garages of anal retentives all over the place.
