Hey, nice thread!
I tried to get the topic started last year, but it didn't work out. I also think that Dresden Files Evocation might be a good fit for the Force (though it might be overcomplicating things a bit. I feel that Dresden Magic is just way more versatile and therefore more in need of a freeform system than the Force). The similar but less fiddly approach would be something along the Control power in Strands of Fate, if anybody has read that.
That being said, I was working on hacking the Force, Dresden Style. Basically instead of Elements you get Control, Sense and Alter powers, which you could Refine. Also, I did model the Dark Side using Lawbreaker stunts and made them requirement for certain Force powers. For example, to use a Lightning attack, one needs "Steeped in the Dark Side", which is basically the [-3] Lawbreaker power. Basically there is a progression from "Temptation of the Dark Side", which acts like Demonic Copilot and has to be taken by any Force User. Once you knocked yourself out with it, it would be replaced by Tainted [-1], touched [-2] and finally steeped [-3].
I was undecided whether using the Attack Option would be a Dark Side act (as using an offensive block) by standard. Also, I got stuck in modelling the Sense (precognition etc.) and Control powers (speed, jump,...). Somehow just using a Maneuver to make yourself "Swift as the Wind" seems lame when there are so many nice Powers in Dresden Files like Inhuman Speed, Cassandra's tears, etc...
Cheers,
