I've come across some shield design transfers for Numidian and Carthaginian shields. I believe these are by little big man studios and they are for 1/72 miniatures. I'm going to have a go at replicating some of the designs on my 10mm Carthage troops, but not sure how well it will go!!
I've linked the shield transfers below, shame that these are for larger scales as they look pretty nice
