It's a matter of rearranging the pixels and hooking the support circuitry in different places. My guess is that sensors are implemented as grids, e.g. may be a "pack" of X*Y pixels and the readout circuitry for the pack. So it should be a matter of rearranging the packs. Truth be told, I like the 24x66 (or 1:2.6) format the best :-) 2:3 is OK, but practically look slight pano'ish to me. 4/3 is better in that sense.
