"here is the leaf spring connection, thinking if I flip it I will have to weld a plate to support it on the back side to hold the spring??"
I would have to think long and hard about that one. In my mind, flipping the axle would would multiply the forces working against the mounting system. If I were to try that, I would use a heavier welder, and order U-Bolts long enough to go through the factory mount. I would make that change before doing anything else. I would load the trailer with twice the weight I think it will ever carry, and beat the snot out of it to see if it will live.
With the trailer sitting level, how far off the ground is the hitch? If you were to flip the axle, how far off the ground would the hitch be then?
I would look into the possibility of making another axle with hubs to match the vehicle's bolt pattern.
