At the very least it would have to be about 1cm or so taller than the K-3 to accommodate the expanded mirror box/sensor and larger viewfinder. Which is pretty much what the CP+ FF mockup looks like to me.
So I guess that ends up being whether you consider the FF mockup as just a modified K-3 body that's about 1cm taller, with a pointy viewfinder hump and minus the headphone jack hump, or a separate "new" body.

I assume you mean getting rid of the separate PDAF system entirely and going with on-sensor. That would mean either going full mirrorless or heavily redesigning the mirror beam splitter to redirect light towards the sensor (which still wouldn't solve the lens mount centering issue by shifting the center of the sensor downwards).
Yeah, I don't think Ricoh is going to spend millions in R&D to bend over backwards making everything somehow fit in the K-3, probably making several performance compromises along the way, when they could just solve everything by simply making the chassis 1cm taller (which is apparently what they did with the mockup). Especially since the rumor is the "K-3 body FF" is the "budget" model.
It's not like that would make it gigantic either. The K-3 and K-5 series are already the smallest in the high end APS-C class. Increasing the height would only make it about the overall size of the D7200 (minus the pointy tip of the viewfinder hump).
