Perhaps Strelets could simply produce a sprue of curved legionary shields so that the pedants among us can do our own modifications? The production costs shouldn't be too high, and I'd certainly be interested in buying several boxes worth...

Try converting them mike, with at least half of the bods it just won´t work, not only that the model ends up ruined but the other available shields eg, hat- too small, Italeri- big hole in the middle, Zvezda - same problem.
Basically, Legionaries-Curved, Auxillaries-Flat.
