To the best of my knowledge all of the Spitfire Mk Vas had cloth ailerons like the Mk I and Mk II did, with the associated poor roll rates.
Nope. As Nrshida mentioned, many Spit 2s operating at the same time as the Spit Vs had metal ailerons retrofitted. Same exact design, just metal covered. Va would have the same ailerons as the Vb and Vc.
I suppose in the ideal AH world you'd have the option to choose the wing, engine type appropriate for the Spit V version needed, full or clipped wings, and maybe Vokes filter.
Not worth it for the MA, but for events it would really help the cause in terms of immersion and historical accuracy. Imagine the whines in a MTO, PTO or CBI event when guys went up in tropicalized Spit V and had to deal with the performance hit from the drag created by that big Vokes filter
