So since I would need to buy the running gears I would be looking at close to $1k for each wagon if I can find cheap running gears (don't find them very often here). Overall I would be looking at close to $10k just for wagons to meet my current setup.

How long does it take you to load the wagons? What about unloading them? And do you park them around the outside edge of the field so the baler doesn't have to work around them?
