I'm also thinking of working Jihahna towards Jedi now... I think i'm going to go with a couple more scout and soldier levels, a couple of adept levels, then start in Jedi. But she will get much of her crucial training strangely enough from This Gand, who has a personality and outlook that would not be easily corrupted by the dark side. Instead of picking a conventional lightsaber style, i think I'd like to continue with her utilising a bayonet, making a lightsaber bayonet. I also noticed that adepts can 'lightsaber proof' their melee weapons, so i'm wondering if she might be able to do that to her blaster rifle to protect it.
I think it would be pretty cool to see a jedi with bayonet parrying a sith lord.
