The problem with double bladed lightsabers is that they have none of the good aspects of a staff of the same length. Keep in mind, pretty much whatever a lightsaber’s blade touches is going to get seared or slagged. Thrusting with one blade, means the other is very awkwardly close to your side. Then, you can’t really do vertical strikes or parry vertical strikes. And the “Oh, but you can strike much faster… BAM BAM BAM BAM!!!” thing… well, that’s about all you can do. Also, a single bladed lightsaber is going to parry those individual and move to the next both faster and more efficiently than you can strike.
Personally, I’d go something more like the concept art for Darth Bane’s Glaive-thing. Maybe a collapsing haft for a second side. You can see the obvious advantage in this HEMA video.
One of the weapons I’ve wanted to see make live action were the discblades as used by the Zeizon Sha. as far as a character’s load out, one big one, and dozes of, like wrist-bangle-thingies, used in a telekinetic sort of fuck-you.
I’m purposefully ignoring the inquisitor’s toys… I’m pretty sure they were actually a joke. (especially at the point that that one dude… used it like a helicopter rotor…)
