In every form of Star Wars media, we've seen that multiple Force users have the ability to work together to accomplish greater feats with the Force than one could alone. However, nothing that evokes this exists in the F&D rules as of yet. So here's my suggested addition:
Under the "Assist Maneuver" section in Conflict and Combat, add the following:
"Force Assist-A character with Force Rating of 1 or higher may spend a maneuver to Commit a <Force Die> and choose another character at engaged range that possesses one or more of the same Force Powers as themselves. On the chosen character's next turn, if he/she would roll a Force Power check for a Force Power he/she shares with the character that performed the Force Assist maneuver, he/she may roll an additional Force Die as part of the check.
A character may only simultaneously benefit from a number of Force Assist maneuvers no greater than his/her Force Rating, and if the character that performed the Force Assist maneuver takes damage before the recipient's next turn, the effect is negated."
I feel this addition could facilitate some really cool scenes that there's few ways to replicate beyond house-rules, and open up some interesting strategies from creative groups.
I realized that, if unchecked, the ability to do this might allow a group of novice force users to start throwing starships around, so I built in the same limits as an Aim maneuver (breaks on damage), as well as just how much assistance one person can have at a time. The fact that both characters have to have the same power is also somewhat of a control valve, since huge amounts of assistance would only be possible in groups where multiple people have the same powers and at least one of them would have to have high FR.
Ultimately, I think it would be a worthwhile addition to an already stellar game:)
