Eesh... be careful if you're going to try something different... and panning kicks and bass is generally considered different. There's all kinds of room to experiment, and that's good, but you should probably leave the kick, bass, and snares up the middle. Anything else and people will fall over while listening to your mixes. The kick and bass combination give more power and punch than any other element except, perhaps, a huge wall of guitars. Treat them as one giant instrument and you'll be on your way to making nice, tight mixes.
