I really like the idea of Fusion Swords as they are presented in the Farsight Enclave Supplement, is there a way to properly integrate them into a list?

The only thing I could come up with so far looks something like this:
Farsight
Brightsword
3x Crisis, 2Fusion or Plasma, Shieldgen + marker or atack drones
Which should be able to deliver a pretty nasty 1,2 punch into TEQ or MEQ, by first shooting and then charging the crippled unit to clean up.

But what would the rest of the list look like? I can't really think of anything which would provide good synergy.

Melee Tau don't work. They aren't supposed to as it is not apart of their core battle doctrine.
