The couple of millimetres needed for a plastic frame won't add any appreciable thickness to the body for operation/grip purposes and will only add a fraction (if any) to the overall size compared to what a lens would add. Let'd face it, the K-01 isn't a pocketable compact and never intended to be. A few millimetres isn't going to matter for something which could make the model immeasurably more popular.
The K-01 is 79mm thick as is, much less than the K-3 (100mm) K-50/500 (97mm) K-30 (97mm) and even the X5 (86mm) which has the tilting screen.
Could be easily done I'm sure.
Probably Mr Newson didn't like the idea.
I'm sorry, but the math just doesn't support that. The K-01 is 79mm
TALL, and 59mm thick. It's 45.46mm (the flange focal distance) from the front edge of the mount to the sensor, leaving 13.54mm for the SR chassis and rear LCD. The LCD glass and circuit board are about 3mm thick, and the SR chassis about 10mm (as I said earlier, even the Q's SR chassis is about 10mm thick). Every tiltable LCD I've been able to measure was about 8mm thick - not counting the rear wall of the body, but even ignoring that, the LCD pocket is sticking 5mm into the body, biting into half of the SR chassis.
I've measured the K100D, K-x, K-r, K-30, and K-5 (front of mount to rear glass - not the spec dimension, which includes the grip and/or eyecup). They were all 63-65mm thick. The K-01 squeezed the mount-to-rear-glass dimension by compressing the main circuit board and moving it from the usual location behind the SR chassis to the side (displacing the battery forward). Now, a body with K-x dimensions, but a K-01's main board, would have space behind the SR chassis perfect for a tiltable LCD.
As for the X-5, that's comparing apples to kumquats. The X-5 doesn't have to preserve the K-mount flange focal distance, freeing up 20mm, maybe more. Plenty of room for a tilt-LCD.
