I agree completely that if Pentax is to go full-frame, it should not be a 'me-too' offering. They will never be able to compete with Canon and Nikon on their own turf; to attempt this would be suicidal. The Pentax offering must be different; and it must play to Pentax's traditional strengths.
To this end I would suggest the following: Pentax should offer a 'small-bodied' (small is, of course, relative) weather-sealed camera that appeals to (as Falcon-eye says) the "image perfectionist." And the affordable way to achieve this is to eliminate (a) auto-focus; and (b) 'movie-mode'. (Those who insist on these features should really consider the Canikon route.)
Let us not forget that the most expensive--and arguably the most coveted-- (small format) full-frame digital camera in the world is the Leica M9-P. And Leica users--obsessed as they are with IQ--seem perfectly happy to live without these 'features'. (Consider, too, the number of manual focus lenses sold by Zeiss and Voigtlander to Canon and Nikon users.)
If image quality is your first concern, then auto-focus and video become much less of a priority.
As for shortage of lenses, I think it all but certain that Zeiss and Voigtlander/Cosina would immediately re-introduce their Pentax mount offerings if there was a Pentax full-frame. And let's think about Pentax's own 'war-chest'.
Does Pentax-Ricoh really need to spend huge amounts of money on R and D when they have design jewels like the A* lenses. I would purchase a new A* 85 or A* 135 in a heartbeat were they to become available.
But what about the 'legacy lens' issue? One forum member suggested that Pentx-Ricoh does not want to maintain lens compatibility because it would lose future sales. I'm not so sure about this. There are many Pentax dslr users whose principal reason for buying Pentax was that they already owned so much Pentax glass. I believe it would be a mistake for Pentax to abandon that user base.
Just imagine: a digital full-frame with real manual focus accuracy; real wide-angle fov; real 35mm dof; and all w/o the inherent limitations of range-finder photography.
Whether or not such a camera should have an anti-aliasing filter or not is debatable. Also debatable is the extent to which the camera should be burdened with 'me-too' features like camera-top lcd displays.
I just hope that Pentax (Ricoh) will consider the history of the brand and get back to basics. This is, to my thinking, Pentax's 'niche'.
