Sure! I'd be into that.
Sword and buckler is one thing I neglected to learn much about in my WMA studies. Now that I'm back into Dagorhir, I'd like to remedy that.
BTW, which flavor of longsword do you do? I'm a Liechtenauer guy, myself. But Fiore is pretty cool stuff, too. It's all fun, as long as you get to crush your opponents, etc.
