Lower cross hanger under plate, designs?

[Titus Marius Secundus]

Hey,
I was wondering if it would be correct to follow an original piece for my scabbard, as the lower cross hanger is just sitting there alone :/ I could use my initiative but I don't want to go on a wrong design! Punching holes would be fine? Or an embossing job is it?

Here's a picture of what I want to copy in a different style.

Regards, and thanks,

Sam
