I could see Veteran Instincts coming back with three changes:
1) It only works in the Activation Phase. You can move before Vader, but you won't shoot before him. Alternately, it can be used in either Activation and Combat Phases, but the effect only lasts for the duration of the phase.
2) It has charges that must be spent at the start of the phase and cannot be recharged, so there's now a strategic decision of when the best time is to use it. The charge mechanic could also allow you to have that one turn of power where you use it in both Activation and Combat phases, but at the cost of burning out your charges faster.
3) The cost increases based on the Initiative level of the pilot equipping it. This means that, yes, Wedge can use it to activate at I7, but he's going to pay 10 points for the ability instead of the 4 points that Biggs might pay to activate at I4.
