No, you'll need a new head. Don't try to build a frankenstein hitch, just go buy a complete one new or used. I had a quick glance at the pictures and I agree it doesn't look right. That drop shank is too much, those bars are way too low. Before you go and start throwing money around and cutting things off your trailer, I would find someone in your area that actually knows what they're doing, buy a different used hitch for cheap, and set it up properly. You could have your problems solved for a couple hundred bucks.
