having a violent nature above and beyond the usual for jedi could be a reason to fail the test of spirit.

Lightsabers are usually an act performed while a padawan and part of the transformation to jedi knight. Until then, younglingslike in the temple were using what is called a training saber and padawans basically borrow a functional saber from their masters. Sometimes the master will build the lightsaber in front of the padawan to show them what to prepare for and then hand the child the one the adult made as a gift.

So if she never even made it to youngling, no saber at all. if she made it to youngling but not padawan, then a practice saber. if a padawan and her master died at order 66, then a functional lightsaber.

But remember, Makutai dont use lightsabers, they use Wan-shen. A pole-arm weapon that is often imbued with the force to resist lightsaber strikes, but only defined as 'a 2 meter pole with a blade on the end'. I've seen this interpreted lots of ways. Some people think of a glaive or naginata others say the image is clearly an axe like a halberd and I once saw a player claim the blade on the end of a stick as a scythe. 

When this gets off the ground, the wookiee's is going to be using his Ryyk blade retooled into this weapon with a collapsible handle as a snap out baton, a lot like a [url=http://ep.yimg.com/ay/yhst-87491460501412/japanese-naginata-spear-1.gif]machete on the end of a stick[/url]. Your character could do something like take the lightsaber components from their old saber and introduce the pieces into the construction of the wan-shen to give it a second life as something new just like she would use her limited jedi training to build upon her makutai training. 

Carrying around a saber is an invitation to stupidity if even an 8 year old slave can recognize an unignighted laser sword on the hip. If it is not dismantled into something like the golden gun (james bond movie staring count dooku ironically, a disassemblable golden handgun made of a gold cigarette case, gold cigarette lighter, gold fountain pen and gold cufflink as the gun's trigger.), which till takes time to assemble, unless you are thinking of the jedi from star wars rebels where he keeps just one piece unattached and snaps them together which takes less time but still identifiable as lightsaber parts.

Not shooting it down, just ideas and information
