A mundane character is certainly doable. Using sum-to-ten, you can take A: Attributes and skills, C: metatype for a human with 7 Edge, and E: magic and resources (spending 10 Karma on extra money lets you start out with 26,000 Nuyen, enough for the basic necessities). So you will have great stats, ample skills, and a high Edge when you get in trouble or are making an important roll.
Long-term viability depends on two things: one, how quickly the runners advance, money-wise (so you can start adding augmentations); and two, how important skills are outside of combat. In a stingy campaign where the main focus is on combat dice pools, this guy still won't be bad, but he will probably be behind the power curve. In a campaign with large cash rewards where a well-rounded skill set is rewarded, this might even be an optimal choice to take - have higher Attributes and more skills instead of augmentations you will quickly be replacing with better stuff shortly.
