I did try that, but I was struggling at Lv5 and had to level up to 7 to get off of Taris. I did at least choose my feats and stats with the expectation of building a strong, single lightsabre wielding guardian. On my first attempted playthrough (well, the first one that got off Taris) I had no idea my character would become a Jedi so I built her to be a heavy weapons & armour specialist. Totally hobbled my character when she got to Dantooine.
I might try level saving at '5' again if I decide to do a dark side playthrough.
