A nice idea, but most Asian cultures went for lighter style shields than the rather clunky oak plank and leather used in Northern Europe. Most were variants of wax boiled hide and cane warped over a mould. There are some nice Middle Eastern/Afghan shields out there, and the Ansar ones are good but very distinctive looking. The Ancient and Medieval Persians used hide covered wicker - so Sparabara/Immortals or even Sassanid shields might be an interesting alternative
