The game mechanics don't prevent its use. You can spend an evade token to add 1 evade result, even if you roll a total of 0 defense dice. You technically "rolled" 0 dice, and you still go through the steps of modifying the result. Spending an evade token adds a green die to the table with the evade side facing up.

Also worth noting, even an agility 0 ship gets to roll bonus defense dice for a range 3 and/or obstructed attacks. This can be very useful for tactical survivability, btw, so keep that in mind when flying a Ghost or Decimator.
