I'd charge a Refresh for using Conviction with Incite Emotion, personally.
Anyway, I just searched the Custom Powers Master List and found this:
Incite Emotion trappings:
Emotion Burst [-1]: Requires At Range trapping. You may take a -2 penalty to your roll in order to have Incite Emotion affect everyone in a zone.
At Long Range [-1]: Requires At Range trapping. You may use Incite Emotion on a target up to three zones away
Resonant Emotion [Incite Emotion Upgrade; -1]
Musts: Lasting Emotion
Attacks and blocks made with Incite Emotion gain a +1 bonus, and aspects placed with Incite Emotion maneuvers are automatically sticky.
Heart-String Virtuoso [Incite Emotion Upgrade; -1]
Musts: Resonant Emotion
When tagging an aspect placed with your Incite Emotion power, you gain a +1 bonus, for a total of +3.
Emotional Control [Incite Emotion Upgrade; -1]
Musts: Incite Emotion
You may use Discipline instead of Deceit or Intimidation for your Incite Emotion power, and gain a +1 bonus when doing so.
Incite Crowd [-1], upgrade to Incite Emotion
You may use Incite Emotion against multiple targets simultaneously, as per the Spray Attack rules, splitting effort between targets, or, for a -2 penalty, against everyone in the zone you occupy, excluding yourself if you wish. The benefit of this upgrade cannot be used in conjunction with the benefit of At Range. Though you may possess both and use them both, you cannot use them both in the same action.
Obviously, this all needs a revision. But maybe it'll serve as inspiration.
