I looked at my Archer panel line decals this morning and I don't think event the widest ones have enough profile, plus there are only three lines so you would need 2-3 sets.
Instead I suggest using 0.010 styrene rod. Once it is down and given a chance to cure here are two ways to make it look like a stamping
—flow thin CA along each side to "fill" each side. You may decide doing this twice will be necessary. When cured fold some #600 sandpaper and run the fold along each edge. I have used this method and the effect is very convincing I think.
—similarly run Testors liquid cement down each side. This will require a substrate of maybe .60 styrene to prevent distortion. Maybe alternate by running the Testors along the top of the rod. This will gradually melt the rod to give it a stamped look.
