How to fill gap from tailgate removal?

[winks]

There is a toe-grabbing, ankle-twisting, leg-breaking, license plate-bending gap between my bumper and where the tailgate used to be.
Has anyone made or found something that can be stepped on to fill the gap?
Thanks,
Dave

Wow that does look large. How about getting some steel plate cut to fit and bolting it up through the underside of the bumper or down through the top, plate would be mounted under the bumper lip? Might not be super load bearing but all you really need by the looks is something to keep you from slipping through.
