Disco 2 Rear bumper bump

Well ive managed to smack my rear near side bumper / fog / reverse lights, i pride myself in actually being able to drive forward and backward and not hit things but for some reason, 3 seperate bumps on that side since January , so now either replace for same or get a metal one made up,
What's the best options, excluding a reversing camera / sensor as my son suggested.
I don't have much dosh to buy a new one but I do have a yard full of metal and my son is a fabricator, just looking for some ideas, something different, maybe with a step?

Second hand bumpers are around £60 ~ £80 & not so difficult to find as intact front bumpers - lol. Reversing sensor kit off ebay about £15.
I've fitted both over the last few years. Far better looking than most steel rear bumpers!
