I've heard of this being done. In fact, Gossamer Gear make some prototypes of a break-down version of their Lightrek pole built with pieces from Titanium Goat.
I tested one of these early poles and had terrible luck. The pole still felt fine but the reinforcing ring where the pole was cut broke free and the pole shattered on an impact.
Gossamer Gear had similar results with some other prototypes and decided to not bring this model to market.
I suspect the flexibility inherint in the Lightrek design was a major factor of this failure. If you make such a conversion, you'll want to really beef up the pole and the area of the cut.
This may be even trickier with the new tapered shafts of the Lightrek 3 (which is a SWEET pole, by the way!)
Best of luck!
