We already know that VI, and all other permanent Initiative boosts, are going away. However, the devs have not ruled out the prospect of temporary initiative changes.
Could this be the future for VI? Instead of a permanent boost, what if it just changes to a single-round (or even single phase) boost that has you spend a charge to gain a temporary +1 or +2 boost to Initiative, or just completely bump you to Initiative 6 for that turn. Luke still isn't as good a pilot as his father, but for one turn he's able to draw on his experience to match up with him.
It seems like it would be both more balanced and more thematic, rewarding players for choosing the right moment to actually use the ability instead of just being on all the time.
