I think the straight answer is no. As has been said, different weapons, different uniforms. You might be able to get away with putting sun helmets on the Afrika Corps and painting them in a more Italian scheme, but it seems a shame not to use actual Italian models seeing as there are so many available at the moment (all in metal though.) Perrys are the cheapest, at £7 for 6, and you can't go wrong with them, really. Warlord have a very comprehensive range, and Empress Minis (in the Abyssinia range) and Artizan are also worth a look, though they are less comprehensive.
