I've fiddled with my domi a bit and I was re-watching the little clone-wars mini series (the ones before the third movie came out).
Watching some fights against Magna guards, it occurred to me that a long bodied staff with short blades, something totaling 6 feet but only have shoto sized blades, would be much more manageable by us mere mortals, and even for certain Jedi, than the 'two sabers bolted together'.
So I'm thinking a pair of decently long MHS hilts with a Yari in between.
"But the staff part would be too easy to get cut through."
No, there are ways around that.
- Certain alloys of Cortosis, while not causing a lightsaber to short out, do prevent it from cutting through the material and are strong enough to make weapons out of. The more raw cortosis isn't very durable overall.
- A Manadorian Iron staff would be resistant, though getting a Mandalorian to make you a lightsaber hilt would be rough.
- Neuranium and Phrik are both very resistant to lightsabers, Phrik more than the first. (Neuranium has the downside of being described as 3-4 times the density of lead, the staff would be physically quite heavy). The Magnaguard staves were made of Phrik.
- As a 'real world' example, if the hilt was made of a superconductor it would have two unique properties which would resist lightsabers by design: 1, a superconductor is the same temperature at all points in the material. If you want to cut through it with a plasma blade you have to keep the blade on it long enough to heat the entire outside of the staff to it's melting point. 2, the lightsaber (sources vary) uses a magnetic containment field. Superconductors eject magnetic fields (until they reach a certain strength) meaning glancing blows might not even touch the staff to heat it up. Once they get close/strong enough, magnetic force lines penetrate in this odd quantum effect that tends to lock the field lines into the superconductor, requiring varying amounts of force to move through it. It's neat because you can turn a magnet with a superconductor hovering over it upside down and it will not budge from the magnet's point of view.
That would give you the wide two handed leverage and variable reach of a staff with the cutting ends of a lightsaber.
