What about comic boxes?, I think boxes for classic size comics are just a bit wider and higher than MOC's so they would be an almost perfect fit stored vertically.
You could stand them up without cases in the boxes 2 MOC's at a time with the bubbles 'face to face' so you can fit more in the box, the boxes are archival safe ( acid free ) and very strong too and can be stacked up high.
