Looking at doing panorama/triptych (or even pentaptych). This would solve the problem of two formats and increase resolution three fold.

The image above is drawn from one EM5 file and with added cropping, so the res is quite low.

Each square needs to stand on it’s own and some zoom induced distortion of scale may be used, but potential?

This also allows me to capture movement in a frame, with time to take supporting frames as needed.

They could also simply be stitched.
