It would be great if you could run some of them on a Sunday and any of the options you describe would be fine. Even if it was just one mission to kick off our usual coops that would work too. No reason why we shouldn't switch sides at will as long as we keep the sides reasonably balanced.
It seems that 3 of us (Sged, Cannon and me couldn't fly any of the Pe2s and there may be more). If you are leaving the Pe2 in, could we have a bomb carrying hurricane.
