I hope you realize that Thiel's designs are time and phase coherent systems. Thiel goes to great effort to design cross-overs that compensate for any driver irregularities. My suggestion would be to leave well enough alone and consider other options. Perhaps different amplification.
Why mess with it, you may get worse sound and if not careful hurt resale value.
