I'd try fuming the Florentine brown one or just dipping the whole thing in it - being that's it's FC and FN03 it won't hurt the plastic.....I store my mix in plastic bottles.

check out this site, I use a couple to colour my brass for IPSC, works a treat

In my youth I started my sculpture career working in art bronze foundries.The most common patina was brown and that was achieved with Ferric Nitrate.
