Thoughts on the "Seize the Initiative" rule?

In Horus Heresy and in older editions of 40k, there was a rule called Seize the Initiative.

Essentially, after everything is deployed and whoever goes first has been established, whoever was going second could make a Seize roll right before the game begins - on a 6 they go first instead. It added a bit of fun unpredictability to the game.

Would you like this rule in the current edition of 40k?
