That it could be.
Jelena has a point in Fix-It, but I doubt that Sunda could levitate her up to the thing (and it would likely just push her down in the process). I was also thinking of maybe using the Force to smash it (maybe with Combat Push?) using Fix-It to figure out where the best place to break it would be. But I imagine she would need to look at it first. I also pushed the 'throwing my lightsaber into it' idea earlier but you said it would just knock the saber down, and if it is electrified it might just shut the saber off.
A point in fix it is certainly better than none at all! No levitating, no, though the top is within jump range.
Now, time is an issue here, and the length of time you take to do things will count. By which I mean you need to make a Strength roll to keep hoding your breathe successflly for every major action you take, and it will get harder as time goes on. So best plan your course of action carefully!
