Can I add a docking port to a ship I already have in space? I'm building my first ever space station around kerbin and I have my KSS core at a decent 250km orbit and when I finally got my refueling module rendezvoued with my Core I found out I stuck on Lateral docking ports instead of radial docking ports. I spent probably close to 1.5 hours getting everything right and I found out I can't even dock. 

Thanks brings me here today, is there a way I can get the bad docking ports off and put on the right ones without relaunching everything into orbit? I don't care what I have to do or how "cheaty" it may be, I just want my screw up fixed the easiesy way.
