lol, as funny as it may seem or sound, i'd make lightsaber nunchucks.
They'd be the size of regular nunchucks. Colors would vary, And special saber proof gloves and upper armor would come with the weapon.
I saw in ep. 3, that Master Kenobi's blade didn't cut through Gen. Grevious's bodyguards staff. I'll use that same substance for the gloves. I'd make the gloves flexible somehow due to the rapid hand/finger movements you'd need handling my saber-nunchucks. And the armor would be needed for nunchuck contact and maneuverability.
How about midi-chloridian fusion?
When 2 midichloridians are collided at the speed great enough, they unite and form 1 bigger trinicloridian, which has a mass of 1.6 midichloridians. The missing 0.4 is released as energy. Heat and light are formed in this reaction. And when formed thrinichloridian is struck by a midichloridian, it shatters into 2 monochloridians and one midichloridian. When monochloridian collide with midichloridians, they form trinichloridians. This reaction goes on and on, until the midichloridians are all transformed into energy.
So we shall make a countainer with two ends. Both ends have storage of midichloridians, which are filtered from the blood plasma found in the galactic blood-bank. Behind the midi-banks, are located two thermal explosives, that produce pressure enough for midichloridians to reach their critical speed. Both streams collide at the middle parth of the bomb.
As a result, we shall see a weapon, galaxy has never seen!
wow. Am I creative...
So tehcnically this is midichloridian fusion, that results a trinicloridian fission. XD
