Dual Wielding was used in combat in the 16th century in Bologna. Buckler and Sword, Sword alone, Sword and Dagger, Sword and cape, Two handed swords, and polearms were used aswell. Simply put, you would place your left sword in a guard and attack with the right, or put your right sword in the guard and attack with the left. It is no different than a sharp, holdable, shield. Certainly this takes away from the flourishes seen in movies, but it is still an elegant play.
As for long and short ranges being taken away from kicks... Well, if I keep using my Italian fencing example, short and long distances were taught separately. Master Achille Marozzo stated that he charged 7 Bolognese pounds for Gioco Stretto plays of the Half Sword (Close range) and another 7 pounds for Gioco Largo plays. Simply put, you should try to treat long and short range as two different techniques. You can avoid being kicked, use footwork and short controlled strikes. Always keep your sword in the enemies presence threatening him. That's all I have to say.
