Troubles with space constraints...wasted corner space

One thing nice about lazy Susan type turn trays is the ability to use a corner somewhat...I have tried to put drawer cabinets but theres still a gap of a corner

I think I could have put train tracks  together or stack some burps or stack the huge premade wing parts of planes.  For now I stuck the lego box container there but the corners are such wasted space.  One idea I've had and started was getting metal pipe the diameter of lego hands so I could attach minifigs to the rods for storage.  It'd be like foosball or lego skewers!

My only worry is damaging the lego hands so that they wont hold accessories anymore
