I have an arc trooper in mind I wanted to run past first. I was thinking a trooper either under Kazdam paradu's or [@Zarkun] the idea is that he acquired a jedi's lightsaber and fitted the blade like a bayonet to his very long Clone rifle to emulate their lightsaber pike style. In an effort to keep pace with the jedi, he requisitions a [url=http://starwars.wikia.com/wiki/Corellian_powersuit] powersuit[/url] made to increase seed and reaction time rather than strength.

BTW, kazdam paradu racticed shien with his lightsaber pike. if that was the form style you were looking for.
